Yogakundalini Upanishad
It is a part of the Krishna Yajurveda. It deals with an exposition of Hatha and Lambika Yogas. It concludes with an account of the non qualified Brahman. The Non-dual Brahman is the quest of all seekers. Though grouped among the minor Upanishads, the Yoga-Kundalini Upanishad is a very important work on Kundalini Yoga. It begins with an analysis of the nature of Chitta. It maintains that Samskaras and Vasanas on the one hand, and Prana, on the other, constitute the causes for the existence of Chitta. If Vasanas are controlled, Prana is automatically controlled. If Prana is controlled, the Vasanas are automatically controlled. The Yoga-Kundalini Upanishad presents methods for the control of Prana. The Yogic student does not deal with Vasanas. He concerns himself with the techniques of controlling the Prana. The three methods given in the Yoga Kundalini Upanishad for the control of Prana are: Mitahara, Asana and Shakti Chalana.
