Yoga Cmai Upaniad belongs to Samaveda tradition. It is an invaluable yogic text for a sincere and dedicated yoga practitioner. A complete guideline is presented in it for gaining spiritual wisdom through yoga sdhan (spiritual practice).
In the beginning, the text describes the six limbs of yoga that are sana, pryma, pratyhra, dhra, dhyna and Samdhi. With the objective of attaining perfection in yoga, it describes various topics directly related to the theory and practice of yoga. The main topics described in this text are essential knowledge of the body elements, knowledge of the six cakras (energy centers), sixteen dhras (foundations), three lakyas (aims), visualization of light at yonisthna, prnic channels, location of prnic channels, circulation of vital energy in the prnic pathways and their functions, momentum of jva (embodied self) along with pra.
The text further explains the exploration of ajap gyatri, penetration of the door to liberation by kualini, the three bandhas, khecari mudr, sign of vajroli, nature of mahmudr, process of the praava japa, oneness of praava and Brahma, meaning of the praava and its syllables, practice of the turiya okra, praava and hasa sdhan and pranava japa for self-realization.
Finally, the text discusses the victory over prna, praava mantra sdhan, perfection in pryma by the purification of the ndis (pric channels/pathways), the specific result of perfection and harmony from each limb of yoga, and the expression of nda (the spontaneous unstruck sound) through the practice of samukhi mudr, practice of pryma, practice of controlling pra, pra the destroyer of all diseases, and withdrawing of senses from their respective sense-objects.
