The Vārṣṇeyādhyātma, which is comprised of chapters 203–210 of the 12th Book of the Mahābhārata, is an early exposition of the practice of Yoga centered on the manas and the bodily channel called manovahā. The importance of the Vārṣṇeyādhyātma’s doctrine for the history of Yoga has not been appropriately acknowledged in previous research and its systematic description of the practice of Yoga has never been studied in its entirety. A careful reading of the text suggests that the Vārṣṇeyādhyātma touches upon (...) the physiological as well as psychological aspects of a human being in the context of the practice of Yoga. This paper attempts to reconstruct the Vārṣṇeyādhyātma’s understanding of the manas and the manovahā channel on the basis of a critical reading of Mahābhārata 12.207.16–29. (shrink)
