The oldest references to the concept of guru are found in the earliest Vedic texts of Hinduism. The guru, and gurukula – a school run by guru, were an established tradition in India by the 1st millennium BCE, and these helped compose and transmit the various Vedas, the Upanishads, texts of various schools of Hindu philosophy, and post-Vedic Shastras ranging from spiritual knowledge to various arts so also specific science and technology. In the tradition of Yoga that was widely followed throughout ancient India, Shiva was worshipped as the first Guru of mankind who imparted the knowledge of yoga to his disciples. By about mid 1st millennium CE, archaeological and epigraphical evidence suggest numerous larger institutions of gurus existed in India, some near Hindu temples, where guru-shishya tradition helped preserve, create and transmit various fields of knowledge. These gurus led broad ranges of studies including Hindu scriptures, Buddhist texts, grammar, philosophy, martial arts, music and painting.

The tradition of the guru is also found in Jainism, referring to a spiritual preceptor, a role typically served by a Jain ascetic. In Sikhism, the guru tradition has played a key role since its founding in the 15th century, its founder is referred to as Guru Nanak, and its scripture as Guru Granth Sahib. The guru concept has thrived in Vajrayāna Buddhism, where the tantric guru is considered a figure to worship and whose instructions should never be violated.

Definition and etymology

The word guru (Sanskrit: गुरु), a noun, connotes "teacher" in Sanskrit, but in ancient Indian traditions it has contextual meanings with significance beyond what teacher means in English. Beyond a teacher of specific knowledge, "guru" in Sanskrit refers to someone who dispels darkness. Here, darkness denotes the ignorance in the person, due to lack of higher knowledge and because of which the person is continuously rotating in cycle of birth-death instead of getting liberated.

Guru is also a "counselor, a sort of parent of mind (Citta) and Self (Atman), who helps mold values (Yamas and Niyamas) and experiential knowledge as much as specific knowledge, an exemplar in life, an inspirational source and who reveals the meaning of life." The word has the same meaning in other languages derived from or borrowing words from Sanskrit, such as Hindi, Marathi, Punjabi, Tamil, Telugu, Kannada, Malayalam, Odia, Bengali, Gujarati and Nepali. The Malayalam term Acharyan or Asan is derived from the Sanskrit word Acharya.

As a noun the word means the imparter of knowledge (jñāna; also Pali: ñāna). As an adjective, it means 'heavy,' or 'weighty,' in the sense of "heavy with knowledge," heavy with spiritual wisdom, "heavy with spiritual weight," "heavy with the good qualities of scriptures and realization," or "heavy with a wealth of knowledge." The word has its roots in the Sanskrit gri (to invoke, or to praise), and may have a connection to the word gur, meaning 'to raise, lift up, or to make an effort'.

Sanskrit guru is cognate with Latin gravis 'heavy; grave, weighty, serious' and Greek βαρύς barus 'heavy'. All three derive from the Proto-Indo-European root *gʷerə-, specifically from the zero-grade form *gʷr̥ə-.

Darkness and light

गुशब्दस्त्वन्धकारः स्यात्‌ रुशब्दस्तन्निरोधकः ।
अन्धकारनिरोधित्वात्‌ गुरुरित्यभिधीयते ॥ १६॥
The syllable gu means darkness, the syllable ru, he who dispels them,
Because of the power to dispel darkness, the guru is thus named.

— Advayataraka Upanishad (100 BCE–300 CE), Verse 16.

A popular etymological theory considers the term "guru" to be based on the syllables gu (गु) and ru (रु), which it claims stands for darkness and "light that dispels it", respectively. The guru is seen as the one who "dispels the darkness of ignorance."

Reender Kranenborg disagrees, stating that darkness and light have nothing to do with the word guru. He describes this as a folk etymology.

Joel Mlecko states, "Gu means ignorance, and Ru means dispeller," with guru meaning the one who "dispels ignorance, all kinds of ignorance", ranging from spiritual to skills such as dancing, music, sports and others. Karen Pechilis states that, in the popular parlance, the "dispeller of darkness, one who points the way" definition for guru is common in the Indian tradition.

In Western Esotericism and the Science of Religion, Pierre Riffard makes a distinction between "occult" and "scientific" etymologies, citing as an example of the former the etymology of 'guru' in which the derivation is presented as gu ("darkness") and ru ('to push away'); the latter he exemplifies by "guru" with the meaning of 'heavy.'
