Yoga Upanishads


Yoga Upanishads are a group of minor Upanishads of Hinduism related to Yoga. There are twenty Yoga Upanishads in the anthology of 108 Upanishads listed in the Muktika anthology. The Yoga Upanishads, along with other minor Upanishads, are generally classified separate from the thirteen major Principal Upanishads considered to be more ancient and from the Vedic tradition.
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 with scholar. According to Mahony, they are likely 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, suggests the following Yoga Upanishads were likely composed in the same period as the didactic parts of the Mahabharata and the chief Sannyasa Upanishads: Brahmabindu, Ksurika, Amritabindu, Brahmavidya, Tejobindu Upanishad, Nadabindu, Yogashikha, Dhyanabindu and Yogatattva. Eliade's suggestion places these in the final centuries of BCE or early centuries of the CE. All these, adds Eliade, were likely composed earlier than the ten or eleven later Yoga Upanishads such as the Yoga-kundalini, Varaha and Pashupatabrahma Upanishads.

Scope

Yoga Upanishads discuss different aspects and kinds of Yoga, ranging from postures, breath exercises, meditation, sound, tantra and others. Some of these topics are not covered in the Bhagavad Gita or Patanjali's Yogasutras.
Many texts describe Yoga as consisting of steps or members and according to Paul Deussen, the important Yoga Upanishads which deal with these are the Brahmavidya, Kshurika, Culika, Nadabindu, Brahmabindu, Amritabindu, Dhyanabindu, Tejobindu, Yogashika, Yogatattva, and Hamsa. These 11 Yoga Upanishads belong to Vedic shakha from the Vedantic point of view. These Upanishads include discussion of ethics , asana, pranayama, pratyahara, dharana, dhyana and samadhi.
