Samatha-vipassanā

Origins and development

Early Buddhism

According to Thanissaro Bhikkhu, "samatha, jhāna, and vipassanā were all part of a single path." According to Keren Arbel, samatha and vipassanā are not specific practices, but qualities of the mind that a practitioner fulfills as they develop the factors of the Noble Eightfold Path, including sati ("mindfulness") and jhāna ("meditation"). In the Sutta Piṭaka the term "vipassanā" is hardly mentioned, while those texts frequently mention jhāna as the meditative practice to be undertaken. As Thanissaro Bhikkhu writes,

When [the Pāli suttas] depict the Buddha telling his disciples to go meditate, they never quote him as saying "go do vipassanā," but always "go do jhāna." And they never equate the word "vipassanā" with any mindfulness techniques. In the few instances where they do mention vipassanā, they almost always pair it with samatha — not as two alternative methods, but as two qualities of mind that a person may "gain" or "be endowed with," and that should be developed together.

According to Vetter and Bronkhorst, dhyāna constituted the original "liberating practice" of the Buddha. Vetter further argues that the Noble Eightfold Path constitutes a collection of practices that prepare one, and lead up to, the practice of dhyāna. Vetter and Bronkhorst further note that dhyāna is not limited to single-pointed concentration, which seems to be described in the first jhāna, but develops into equanimity and mindfulness, "born from samādhi." Wynne notes that one is then no longer absorbed in concentration, but is mindfully aware of objects while being indifferent to them, "directing states of meditative absorption towards the mindful awareness of objects."

A number of suttas mention samatha and vipassanā as mental qualities that are to be developed in tandem. In SN 43.2, the Buddha states: "And what, bhikkhus, is the path leading to the unconditioned? Serenity and insight..." In SN 35.245, the Kimsuka Tree Sutta, the Buddha provides an elaborate metaphor in which serenity and insight are "the swift pair of messengers" who deliver the message of nibbāna (Pāli; Skt.: nirvāṇa) via the noble eightfold path:

These two qualities have a share in clear knowing. Which two? Tranquility (samatha) & insight (vipassanā).

When tranquility is developed, what purpose does it serve? The mind is developed. And when the mind is developed, what purpose does it serve? Passion is abandoned.
When insight is developed, what purpose does it serve? Discernment is developed. And when discernment is developed, what purpose does it serve? Ignorance is abandoned.

Defiled by passion, the mind is not released. Defiled by ignorance, discernment does not develop. Thus from the fading of passion is there awareness-release. From the fading of ignorance is there discernment-release.

Ven. Ānanda reports that people attain arahantship in one of four ways:

Friends, whoever — monk or nun — declares the attainment of arahantship in my presence, they all do it by means of one or another of four paths. Which four?
There is the case where a monk has developed insight preceded by tranquility. [...]
Then there is the case where a monk has developed tranquillity preceded by insight. [...]
Then there is the case where a monk has developed tranquillity in tandem with insight. [...]
Then there is the case where a monk's mind has its restlessness concerning the Dhamma [Comm: the corruptions of insight] well under control.

Disjunction of samatha and vipassanā

Buddhaghosa, in his influential Theravāda scholastic treatise Visuddhimagga, states that jhāna is induced by samatha, and then jhāna is reflected upon with mindfulness, becoming the object of vipassanā, with the reflector realizing that jhāna is marked by the three characteristics. One who uses this method is referred to as a "tranquility worker" (Pāḷi: samatha yānika). However, modern Buddhist teachers such as Henepola Gunaratana state that there is virtually no evidence of this method in the Pāḷi suttas. A few suttas describe a method of "bare insight", or "dry insight" where only vipassanā is practiced, examining ordinary physical and mental phenomena to discern the three marks. Gombrich and Brooks argue that the distinction as two separate paths originates in the earliest interpretations of the Sutta Pitaka, not in the suttas themselves.

According to Richard Gombrich, a development took place in early Buddhism resulting in a change in doctrine that considered prajñā to be an alternative means to awakening, alongside the practice of meditation. The suttas contain traces of ancient debates between Mahāyāna and Theravāda schools concerning the interpretation of the teachings and the development of insight. Out of these debates developed the idea that bare insight suffices to reach liberation, by discerning the three marks (qualities) of (human) existence (tilakkhaṇa), namely dukkha (suffering), anattā (non-self), and anicca (impermanence). Thanissaro Bikkhu also argues that samatha and vipassanā have a "unified role," whereas "[t]he Abhidhamma and the Commentaries, by contrast, state that samatha and vipassanā are two distinct meditation paths."

Gunaratana notes that "[t]he classical source for the distinction between the two vehicles of serenity and insight is the Visuddhimagga." Ajahn Brahm (who, like Bhikkhu Thanissaro, is of the Thai Forest Tradition) writes that

Some traditions speak of two types of meditation, insight meditation (vipassanā) and calm meditation (samatha). In fact the two are indivisible facets of the same process. Calm is the peaceful happiness born of meditation; insight is the clear understanding born of the same meditation. Calm leads to insight and insight leads to calm."

Theravāda and the vipassanā movement

By the tenth century meditation was no longer practiced in the Theravada tradition, due to the belief that Buddhism had degenerated, and that liberation was no longer attainable until the coming of the future Buddha, Maitreya. It was reinvented in Myanmar (Burma) in the 18th century by Medawi (1728–1816), leading to the rise of the Vipassanā movement in the 20th century, reinventing vipassanā meditation, developing simplified meditation techniques (based on the Satipatthana sutta, the Ānāpānasati Sutta, the Visuddhimagga, and other texts), and emphasizing satipaṭṭhāna and bare insight. In this approach, samatha is regarded as a preparation for vipassanā, pacifying the mind and strengthening concentration, so that insight into impermanence can arise, which leads to liberation. Ultimately, these techniques aim at stream entry, which safeguards future development towards full awakening, despite the degenerated age we live in.

Samatha

According to the Theravāda tradition, samatha refers to techniques that help to calm the mind. Samatha is thought to be developed by samādhi, interpreted by the Theravāda commentatorial tradition as concentration-meditation, the ability to rest the attention on a single object of perception. One of the principal techniques for this purpose is mindfulness of breathing (Pāḷi: ānāpānasati). It is commonly interpreted that Samatha should necessarily be practiced as a prelude to and in conjunction with wisdom practices.

Objects of samatha-meditation

Some meditation practices, such as contemplation of a kasiṇa object, favor the development of samatha; others, such as contemplation of the aggregates, are conducive to the development of vipassanā; while others, such as mindfulness of breathing, are classically used for developing both mental qualities.

The Visuddhimagga (5th century CE) mentions forty objects of meditation. Mindfulness (sati) of breathing (ānāpāna: ānāpānasati; S. ānāpānasmṛti) is the most common samatha practice (though this term is also used for vipassanā meditation). Samatha can include other samādhi practices as well.

Signs and stages of joy in samatha-meditation

Theravāda Buddhism describes the development of samatha in terms of three successive mental images or 'signs' (nimitta) and five stages of joy (Pīti). According to the Theravāda-tradition, pīti, a feeling of joy, gladness or rapture, arises from the abandonment of the five hindrances in favor of concentration on a single object. These stages are outlined by the Theravāda exegete Buddhaghosa in his Visuddhimagga (also in Atthasālinī) and the earlier Upatissa (author of the Vimuttimagga). Following the establishment of access concentration (upacāra-samādhi), one can enter the four jhānas, powerful states of joyful absorption in which the entire body is pervaded with pīti.

Variations in samatha

In the Theravāda tradition various understandings of samatha exist:

• In Sri Lanka samatha includes all those meditations that are directed at static objects.
• In Burma, samatha comprises all concentration practices aimed at calming the mind.
• The Thai Forest tradition deriving from Ajahn Mun and popularized by Ajahn Chah stresses the inseparability of samatha and vipassanā, and the essential necessity of both practices.

Vipassanā

In modern Theravāda, liberation is thought to be attained by insight into the transitory nature of phenomena. This is accomplished by establishing sati (mindfulness) and samatha through the practice of ānāpānasati (mindfulness of breathing), using mindfulness for observing the impermanence in the bodily and mental changes, to gain insight (P: vipassanā, S: vipaśyanā; P: paññā, S: prajñā) into the true nature of phenomena.

Vipassanā movement

The term vipassanā is often conflated with the Vipassanā Movement, which popularised new vipassanā teachings and practice. It started in the 1950s in Burma, but has gained wide renown mainly through American Buddhist teachers such as Joseph Goldstein, Tara Brach, Gil Fronsdal, Sharon Salzberg, and Jack Kornfield. The movement has a wide appeal due to being inclusive of different Buddhist and non-buddhist wisdom, poetry as well as science. It has together with the modern American Zen tradition served as one of the main inspirations for the "mindfulness movement" as developed by Jon Kabat-Zinn and others. The Vipassanā Movement, also known as the Insight Meditation Movement, is rooted in Theravāda Buddhism and the revival of meditation techniques, especially the "New Burmese Method", the Thai Forest Tradition, and modern influences on the traditions of Sri Lanka, Burma, Laos, and Thailand.

In the Vipassanā Movement, the emphasis is on the Satipatthana Sutta and the use of mindfulness to gain insight into the impermanence of the self. It argues that the development of strong samatha can be disadvantageous, a stance for which the Vipassana Movement has been criticised, especially in Sri Lanka. The "New Burmese Method" was developed by U Nārada (1868–1955), and popularised by Mahasi Sayadaw (1904–1982) and Nyanaponika Thera (1901–1994). Other influential Burmese proponents include Ledi Sayadaw and Mogok Sayadaw as well as Mother Sayamagyi and S. N. Goenka, who were both students of Sayagyi U Ba Khin. Influential Thai teachers include Ajahn Chah and Buddhadasa. A well-known Indian teacher is Dipa Ma.

Stages of practice

Practice begins with the preparatory stage, the practice of śīla (virtue): giving up worldly thoughts and desires. Jeff Wilson notes that morality is a quintessential element of Buddhist practice, and is also emphasized by the first generation of post-war western teachers. However, in the contemporary mindfulness movement, morality as an element of practice has been mostly discarded, "mystifying" the origins of mindfulness.

The practitioner then engages in ānāpānasati (mindfulness of breathing), which is described in the Satipatthana Sutta as going into the forest and sitting beneath a tree to simply watch the breath: If the breath is long, to notice that the breath is long, if the breath is short, to notice that the breath is short. In the "New Burmese Method", the practitioner attends to any arising mental or physical phenomenon, engaging in vitarka, noting or naming physical and mental phenomena (e.g. "breathing, breathing"), without engaging the phenomenon with further conceptual thinking. By noticing the arising of physical and mental phenomena, the meditator becomes aware how sense impressions arise from the contact between the senses and physical and mental phenomena, as described in the five skandhas and paṭiccasamuppāda. According to Sayadaw U Pandita, one's awareness and observation of these sensations is de-coupled from any kind of physical response, which reconditions one's impulsive responses to stimuli, such that one is less likely to physically or emotionally overreact to the happenings of the world.

The practitioner also becomes aware of the incessant changes involved in breathing, and the arising and passing away of mindfulness. This noticing is accompanied by reflections on causation and other Buddhist teachings, leading to insight into dukkha, anattā, and anicca. When these three characteristics have been comprehended, reflection subdues, and the process of noticing accelerates, noting phenomena in general, without necessarily naming them.

According to Thai meditation master Ajahn Lee, the practice of both samatha and vipassanā together allows one to achieve various mental powers and gnosis (Pāḷi: abhiññā), including the attainment of nirvāṇa, whereas the practice of vipassanā alone allows for the achievement of nirvāṇa, but no other mental powers or gnosis.

Vipassanā jhānas

Vipassanā jhānas are stages that describe the development of samatha in vipassanā meditation practice as described in modern Burmese Vipassanā meditation. Mahasi Sayadaw's student Sayadaw U Pandita described the four vipassanā jhānas as follows:

1. The meditator first explores the body/mind connection as one nonduality, discovering the three characteristics. The first jhāna consists in seeing these points and in the presence of vitarka and vicara. Phenomena reveal themselves as arising and falling away.
2. In the second jhāna, the practice seems effortless. Vitarka and vicara both disappear.
3. In the third jhāna, pīti, the joy, disappears too: there is only happiness (sukha) and concentration.
4. The fourth jhāna arises, characterized by purity of mindfulness due to equanimity. The practice leads to direct knowledge. The comfort disappears because the dissolution of all phenomena is clear. The practice shows every phenomenon as unstable, transient, disenchanting. The desire of freedom takes place.

Criticism

Samatha meditation and jhāna (dhyāna) are often considered synonymous by modern Theravāda, but the four jhānas involve a heightened awareness, instead of a narrowing of the mind.

Vetter notes that samādhi may refer to the four stages of dhyāna meditation, but that only the first stage refers to strong concentration, from which arise the other stages, which include mindfulness.

According to Richard Gombrich, the sequence of the four rūpa-jhānas describes two different cognitive states. Gombrich and Wynne note that, while the second jhāna denotes a state of absorption, in the third and fourth jhāna one comes out of this absorption, being mindfully aware of objects while being indifferent to it. According to Gombrich, "the later tradition has falsified the jhāna by classifying them as the quintessence of the concentrated, calming kind of meditation, ignoring the other – and indeed higher – element." Alexander Wynne further explains that the dhyāna-scheme is poorly understood. According to Wynne, words expressing the inculcation of awareness, such as sati, sampajāno, and upekkhā, are mistranslated or understood as particular factors of meditative states, whereas they refer to a particular way of perceiving the sense objects.

Northern tradition

The north Indian Buddhist traditions like the Sarvastivada and the Sautrāntika practiced meditation as outlined in texts like the Abhidharmakośakārikā of Vasubandhu and the Yogācārabhūmi-śāstra. The Abhidharmakośakārikā states that vipaśyanā is practiced, once one has reached samādhi ("absorption"), by cultivating the four foundations of mindfulness (smṛtyupasthāna). This is achieved, according to Vasubandhu,

[b]y considering the unique characteristics (svālakṣaṇa) and the general characteristics (sāmānyalakṣaṇā) of the body, sensation, the mind, and the dharmas.

"The unique characteristics" means its self nature (svabhāva).

"The general characteristics" signifies the fact that "All conditioned things are impermanent; all impure dharmas are suffering; and that all the dharmas are empty (śūnya) and not-self (anātmaka).

Asaṅga's Abhidharma-samuccaya states that the practice of śamatha-vipaśyanā is a part of the beginning of a Bodhisattva's path, in the first "path of preparation" (sambhāramarga).

The Sthavira nikāya, one of the early Buddhist schools from which the Theravāda tradition originates, emphasized sudden insight: "In the Sthaviravada [...] progress in understanding comes all at once, 'insight' (abhisamaya) does not come 'gradually' (successively—anapurva)."

The Mahāsāṃghika, another one of the early Buddhist schools, had the doctrine of ekakṣaṇacitta, "according to which a Buddha knows everything in a single thought-instant". This process however, meant to apply only to the Buddha and paccekabuddhas. Lay people may have to experience various levels of insights to become fully enlightened.

Mahāyāna

The later Indian Mahāyāna scholastic tradition, as exemplified by Shantideva's Bodhisattvacaryāvatāra, saw śamatha as a necessary prerequisite to vipaśyanā. Thus, one needed to first begin with calm abiding meditation, and then proceed to insight. In the Pañjikā commentary of Prajñākaramati (Wylie: shes rab 'byung gnas blo gros) on the Bodhisattvacaryāvatāra, vipaśyanā is defined simply as "wisdom (prajñā) that has the nature of thorough knowledge of reality as it is.

Śamatha

A number of Mahāyāna sūtras address śamatha, usually in conjunction with vipaśyanā. One of the most prominent, the Cloud of Jewels Sutra (Ārya Ratnamegha Sutra, Tib. phags-pa dkon-mchog sprin-gyi mdo, Chinese 寶雲經 T658, 大乘寶雲經 T659) divides all forms of meditation into either śamatha or vipaśyanā, defining śamatha as "single-pointed consciousness" and vipaśyanā as "seeing into the nature of things."

The Sūtra Unlocking the Mysteries (Samdhinirmocana Sūtra), a yogācāra sūtra, is also often used as a source for teachings on śamatha. The Samādhirāja Sūtra is often cited as an important source for śamatha instructions by the Kagyu tradition, particularly via the commentary of Gampopa, although scholar Andrew Skilton, who has studied the Samādhirāja Sūtra extensively, reports that the sūtra itself "contains no significant exposition of either meditational practices or states of mind."

Vipassana—prajñā and śūnyatā

The Mahayana tradition emphasizes prajñā, insight into śūnyatā, dharmatā, the two truths doctrine, clarity and emptiness, or bliss and emptiness:

[T]he very title of a large corpus of early Mahayana literature, the Prajnaparamita, shows that to some extent the historian may extrapolate the trend to extol insight, prajñā, at the expense of dispassion, virāga, the control of the emotions.

The Mahayana Akṣayamati-nirdeśa refers to vipaśyanā as seeing phenomena as they really are—that is, empty, without self, nonarisen, and without grasping. The Prajnaparamita sūtra in 8,000 lines states that the practice of insight is the non-appropriation of any dharmas, including the five aggregates:

So too, a Bodhisattva coursing in perfect wisdom and developing as such, neither does nor even can stand in form, feeling, perception, impulse, and consciousness... This concentrated insight of a Bodhisattva is called "the non-appropriation of all dharmas".

Although Theravāda and Mahayana are commonly understood as different streams of Buddhism, their emphasis on insight is a common denominator: "In practice and understanding Zen is actually very close to the Theravāda Forest Tradition even though its language and teachings are heavily influenced by Taoism and Confucianism."

East Asian Mahāyāna

Chinese Buddhism

In Chinese Buddhism, the works of Tiantai master Zhiyi (such as the Mohe Zhiguan, "Great śamatha-vipaśyanā") are some of the most influential texts to discuss vipaśyanā meditation from a Mahayana perspective. Zhiyi teaches the contemplation of the skandhas, āyatanas, dhātus, kleshas, false views, and several other elements. Likewise the influential text called the Awakening of Faith in the Mahayana has a section on calm and insight meditation. It states:

He who practices "clear observation" should observe that all conditioned phenomena in the world are unstationary and are subject to instantaneous transformation and destruction; that all activities of the mind arise and are extinguished from moment to moment; and that, therefore, all of these induce suffering. He should observe that all that had been conceived in the past was as hazy as a dream, that all that is being conceived in the future will be like clouds that rise up suddenly. He should also observe that the physical existences of all living beings in the world are impure and that among these various filthy things there is not a single one that can be sought after with joy.

Chan/Zen

The Zen tradition advocates the simultaneous practice of śamatha and vipaśyanā, and this is called the practice of silent illumination. The classic Chan text known as the Platform Sutra states:

Calming is the essence of wisdom. And wisdom is the natural function of calming [i.e., prajñā and samādhi]. At the time of prajñā, samādhi exists in that. At the time of samādhi, prajñā exists in that. How is it that samādhi and prajñā are equivalent? It is like the light of the lamp. When the lamp exists, there is light. When there is no lamp, there is darkness. The lamp is the essence of light. The light is the natural function of the lamp. Although their names are different, in essence, they are fundamentally identical. The teaching of samādhi and prajñā is just like this.

Chan Buddhism emphasizes sudden insight (subitism), though in the Chan tradition, this insight is to be followed by gradual cultivation. This "gradual training" is expressed in teachings as the Five Ranks of enlightenment, the Ten Bulls illustrations that detail the steps on the path, the "Three Mysterious Gates" of Linji, and the "four ways of knowing" of Hakuin Ekaku.

Indo-Tibetan tradition

In Tibetan Buddhism, the practice of śamatha and vipaśyanā is strongly influenced by the Mahāyāna text called the Bhavanakrama of Indian master Kamalaśīla. Kamalaśīla defines vipaśyanā as "the discernment of reality" (bhūta-pratyavekṣā) and "accurately realizing the true nature of dharmas".

According to Thrangu Rinpoche, when śamatha and vipaśyanā are combined (as in the mainstream Mādhyamaka approach of Shantideva and Kamalashila), through śamatha disturbing emotions are abandoned, which thus facilitates vipaśyanā, "clear seeing". Vipaśyanā is cultivated through reasoning, logic, and analysis in conjunction with śamatha.

In contrast, in the siddha tradition of the direct approach of Mahamudra and Dzogchen, vipaśyanā is ascertained directly through looking into one's own mind. After this initial recognition of vipaśyanā, the steadiness of śamatha is developed within that recognition. According to Thrangu Rinpoche, it is also common in the direct approach to first develop enough śamatha to serve vipaśyanā. Dzogchen Ponlop Rinpoche charts the developmental relationship of the practices of śamatha and vipaśyanā this way:

The ways these two aspects of meditation are practised is that one begins with the practice of shamatha; on the basis of that, it becomes possible to practice vipashyana or lhagthong. Through one's practice of vipashyana being based on and carried on in the midst of shamatha, one eventually ends up practicing a unification [yuganaddha] of shamatha and vipashyana. The unification leads to a very clear and direct experience of the nature of all things. This brings one very close to what is called the absolute truth.

Samatha

Tibetan writers usually define samatha practice as when one's mind remains fixed on a single object without moving. Dakpo Tashi Namgyal for example, defines samatha as:

by fixing the mind upon any object so as to maintain it without distraction... by focusing the mind on an object and maintaining it in that state until finally it is channeled into one stream of attention and evenness.

According to Geshe Lhundup Sopa, samatha is:

just a one-pointedness of mind (cittaikāgratā) on a meditative object (ālambana). Whatever the object may be... if the mind can remain upon its object one-pointedly, spontaneously and without effort (nābhisaṃskāra), and for as long a period of time as the meditator likes, it is approaching the attainment of meditative stabilization (śamatha).

Śamatha furthers the right concentration aspect of the noble eightfold path. The successful result of śamatha is sometimes characterized as meditative absorption (samādhi, ting nge ’dzin) and meditative equipoise (samāhita, mnyam-bzhag), and as freedom from the five obstructions (āvaraṇa, sgrib-pa). It may also result in the siddhis of clairvoyance (abhijñā, mgon shes) and magical emanation (nirmāṇa, sprul pa).

According to Culadasa, "Samatha has five characteristics: effortlessly stable attention (samādhi), powerful mindfulness (sati), joy (pīti), tranquility (passaddhi), and equanimity (upekkhā). The complete state of samatha results from working with stable attention (samādhi) and mindfulness (sati) until joy emerges. Joy then gradually matures into tranquility, and equanimity arises out of that tranquility. A mind in samatha is the ideal instrument for achieving Insight and Awakening". The idea here is that in order to achieve awakening, you have to master both attention, and peripheral awareness. Such as focusing on the breath and being aware of one's peripheral awareness simultaneously.

Nine Stages of Tranquility

This formulation is found in various Yogācāra sources such as the Abhidharmasamuccaya and the Śrāvakabhūmi chapter of the Yogācārabhūmi-śāstra. It is also found in the Mahāyānasūtrālaṅkāra, which shows considerable similarity in arrangement and content to the Bodhisattva-bhūmi. In this scheme, śamatha practice is said to progress through nine "mental abidings" or "nine stages of training the mind" (Skt. navākārā cittasthiti, Tib. sems gnas dgu), leading to śamatha proper (the equivalent of "access concentration" in the Theravāda system), and from there to a state of meditative concentration called the first dhyāna (Pāli: jhāna; Tib. bsam gtan) which is often said to be a state of tranquility or bliss.

The "Nine Mental Abidings" as described by Kamalaśīla are:

1. Placement of the mind (Skt. cittasthāpana, Tib. འཇོག་པ – sems ’jog-pa) occurs when the practitioner is able to place their attention on the object of meditation, but is unable to maintain that attention for very long. Distractions, dullness of mind and other hindrances are common.
2. Continuous placement (Skt. samsthāpana, Tib. རྒྱུན་དུ་འཇོག་པ – rgyun-du ‘jog-pa) occurs when the practitioner experiences moments of continuous attention on the object before becoming distracted. According to B. Alan Wallace, this is when the meditator can maintain attention on the meditation object for about a minute.
3. Repeated placement (Skt. avasthāpana, Tib. བླན་ཏེ་འཇོག་པ – slan-te ’jog-pa) is when the practitioner's attention is fixed on the object for most of the practice session; and, further, he or she is able both to immediately realize when his or her mental hold on the object has been lost, and to restore that attention quickly. Sakyong Mipham Rinpoche suggests that being able to maintain attention for 108 breaths is a good benchmark for this stage has been reached.
4. Close placement (Skt. upasthāpana, Tib. ཉེ་བར་འཇོག་པ – nye-bar ’jog-pa) occurs when the practitioner is able to maintain attention throughout the entire meditation session (an hour or more) without losing their mental hold on the meditation object at all. In this stage, the practitioner achieves the power of mindfulness. Nevertheless, this stage still contains subtle forms of excitation and dullness or laxity.
5. Taming (Skt. damana, Tib. དུལ་བར་བྱེད་པ – dul-bar byed-pa) is the level wherein the practitioner achieves deep tranquility of mind, but must still be watchful for subtle forms of laxity or dullness—peaceful states of mind which may be misinterpreted as the desired calm abiding. By focusing on the future benefits of gaining śamatha, the practitioner can "uplift" (Tib. gzengs-bstod) their mind and become more focused and clear.
6. Pacifying (Skt. śamana, Tib. ཞི་བར་བྱེད་པ་ – zhi-bar byed-pa) is the stage during which subtle mental dullness or laxity is no longer a great difficulty, but the practitioner is yet prone to subtle excitements which arise at the periphery of meditative attention. B. Alan Wallace contends that this stage is achieved only after thousands of hours of rigorous training.
7. Fully pacifying (Skt. vyupaśamana, Tib. རྣམ་པར་ཞི་བར་བྱེད་པ་ – nye-bar zhi-bar byed-pa) is a refinement of the previous state; although the practitioner may still experience subtle excitement or dullness, they are rare, and the practitioner can easily recognize and pacify them.
8. Single-pointing (Skt. ekotīkarana, Tib. རྩེ་གཅིག་ཏུ་བྱེད་པ་ – rtse-gcig-tu byed-pa) is the penultimate "abiding"; this is the stage of practice at which the practitioner can reach high levels of concentration with only a slight effort, and without being interrupted by even subtle laxity or excitement during the entire meditation session.
9. Balanced placement (Skt. samādhāna, Tib. མཉམ་པར་འཇོག་པ་བྱེད་པ་ – mnyam-par ’jog-pa) is the final stage of śamatha practice, in this model, and entails that the meditator may now effortlessly reach absorbed concentration (Skt. samadhi, Tib. ting-nge-‘dzin) and maintain it for about four hours without any interruption whatsoever.
10. Śamatha (Tib. ཞི་གནས་ – shyiné) is, as the culmination of this practice, sometimes listed as a tenth stage.

Vipassana

Indian Mahāyāna Buddhism employed both deductive investigation (applying ideas to experience) and inductive investigation (drawing conclusions from direct experience) in the practice of vipaśyanā. (These correspond respectively to the "contemplative forms" and "experiential forms" in the Theravāda school described above.) According to Leah Zahler, only the tradition of deductive analysis in vipaśyanā was transmitted to Tibet in the sūtrayāna context. One scholar describes his approach thus: "the overall picture painted by Kamalaśīla is that of a kind of serial alternation between observation and analysis that takes place entirely within the sphere of meditative concentration" in which the analysis portion consists of Madhyamaka reasonings. In Tibet direct examination of moment-to-moment experience as a means of generating insight became exclusively associated with vajrayāna.

Mahāmudrā and Dzogchen

Samatha is approached somewhat differently in the mahāmudrā tradition as practiced in the Kagyu lineage. As Traleg Kyabgon Rinpoche explains,

In the practice of Mahamudra tranquility meditation [...] we treat all thoughts as the same in order to gain sufficient distance and detachment from our current mental state, which will allow us to ease naturally into a state of tranquility without effort or contrivance [...] In order for the mind to settle, we need to suspend the value judgments that we impose on our mental activities [...] it is essential that we not try to create a state of tranquility but allow the mind to enter into tranquility naturally. This is an important notion in the Mahamudra tradition, that of nondoing. We do not do tranquility meditation, we allow tranquility to arise of its own accord, and it will do so only if we stop thinking of the meditative state as a thing that we need to do actively [...] In a manner of speaking, catching yourself in the act of distraction is the true test of tranquility meditation, for what counts is not the ability to prevent thoughts or emotions from arising but the ability to catch ourselves in a particular mental or emotional state. This is the very essence of tranquility meditation [in the context of Mahāmudrā] [...] The Mahamudra style of meditation does not encourage us toward the different levels of meditative concentration traditionally described in the exoteric meditation manuals [...] From the Mahamudra point of view, we should not desire meditative equipoise nor have an aversion to discursive thoughts and conflicting emotions but view both of these states with equanimity. Again, the significant point is not whether meditative equipoise is present but whether we are able to maintain awareness of our mental states. If disturbing thoughts do arise, as they certainly will, we should simply recognize these thoughts and emotions as transient phenomena.

For the Kagyupa, in the context of mahāmudrā, śamatha by means of mindfulness of breathing is thought to be the ideal way for the meditator to transition into taking the mind itself as the object of meditation and generating vipaśyanā on that basis.

Quite similar is the approach to śamatha found in dzogchen semde (Sanskrit: mahāsandhi cittavarga). In the semde system, śamatha is the first of the four yogas (Tib. naljor, Wylie: rnal-’byor), the others being vipaśyanā (Wylie: lhag-mthong), nonduality (advaya, Tib. nyime,Wylie: gnyis-med), and spontaneous presence (anābogha or nirābogha, Tib. lhundrub, Wylie: lhun-grub). These parallel the four yogas of mahāmudrā.

Ajahn Amaro, a longtime student in the Thai Forest Theravādin tradition of Ajahn Chah, has also trained in the dzogchen semde śamatha approach under Tsoknyi Rinpoche. He found similarities in the approaches of the two traditions to śamatha.

Mahāmudrā and Dzogchen use vipaśyanā extensively. This includes some methods of the other traditions, but also their own specific approaches. They place a greater emphasis on meditating on symbolic images. Additionally in the Vajrayāna (tantric) path, the true nature of mind is pointed out by the guru, and this serves as a direct form of insight.

Similar practices in other religions

Meditations from other religious traditions may also be recognised as samatha meditation, that differ in the focus of concentration. In this sense, samatha is not a strictly Buddhist meditation. Samatha, in its single-pointed focus and concentration of mind, is cognate with the sixth "limb" of aṣṭāṅga yoga/rāja yoga, which is concentration (dhāraṇā).
