The Yoga-Kundalini Upanishad is listed in the Muktika canon of 108 Upanishads. Since this canon was fixed in the year 1656, it is known that the Yoga-KundaliniUpanishad was compiled in the first half of the 17th century at the latest. The Upanishad more likely dates to the 16th century, as do other Sanskrit texts which treatkundalini as a technical term in tantric yoga, such as the Ṣaṭ-cakra-nirūpana and the Pādukā-pañcaka. These latter texts were translated in 1919 by John Woodroffeas The Serpent Power: The Secrets of Tantric and Shaktic Yoga. In this book, he was the first to identify “Kundalini yoga” as a particular form of Tantrik Yoga, also known as Laya Yoga.
The Yoga-Kundalini and the Yogatattva are closely related texts from the school of Hatha yoga. They both draw heavily on the Yoga Yajnavalkya (c. 13th century),as does the foundational Hatha Yoga Pradipika. They are part of a tendency of syncretism combining the tradition of yoga with other schools of Hindu philosophy during the 15th and 16th centuries. The Yoga-Kundalini Upanishad itself consists of three short chapters; it begins by stating that Chitta (consciousness) is controlled by Prana, and it’s controlled by moderate food, postures and Shakti-Chala (I.1-2). Verses I.3-6 explain the concepts of moderate food and concept, and verse I.7 introduces Kundalini as the name of the Shakti under discussion:
- I.7. The Sakti (mentioned above) is only Kundalini. A wise man should take it up from its place (Viz., the navel, upwards) to the middle of the eyebrows. This is called Sakti-Chala.
- I.8. In practising it, two things are necessary, Sarasvati-Chalana and the restraint of Prana (breath). Then through practice, Kundalini yoga in newzeland (which is spiral) becomes straightened.
