Yoga Upanishads

The Yoga Upanishads deal with the theory and practice of Yogic techniques, with varied emphasis on methodology and meditation, but with some shared ideas. They contrast from other groups of minor Upanishads, such as the Samanya Upanishads which are of a generic nature, the Sannyasa Upanishads which focus on the Hindu renunciation and monastic practice, the Shaiva Upanishads which highlight aspects of Shaivism, the Vaishnava Upanishads which highlight Vaishnavism, and the Shakta Upanishads which highlight Shaktism.

Date

The composition date of each Yoga Upanishad is unclear, and estimates on when they were composed vary among scholars. According to Mahony, they likely are dated between 100 BC and 1100 AD. However, Gavin Flood dates the Yoga Upanishads to the 100 BCE to 300 CE period. According to James Mallinson, some Yoga Upanishads were revised in the eighteenth century to incorporate the Hatha Yoga ideas of the Hindu Natha sub-tradition.

Mircea Eliade states that textual style, archaic language and the mention of some Yoga Upanishads in other Indian texts suggest the following Yoga Upanishads were likely composed in the same period as the didactic parts of the Mahabharata and the chief Sannyasa Upanishads: Brahmabindu (probably composed about the same time as Maitri Upanishad), Ksurika, Amritabindu, Brahmavidya, Tejobindu Upanishad, Nadabindu, Yogashikha, Dhyanabindu and Yogatattva. Eliade's suggestion places these in the final BCE centuries or early CE centuries. All these, adds Eliade, likely were composed earlier than the ten or eleven later Yoga Upanishads such as the Yoga-kundalini, Varaha and Pashupatabrahma Upanishads.
