Though scholarship on diverse methods of yoga in the Indian traditions abounds, there has not been sufficient research that examines the traditions of yoga in the purāṇas. The present paper explores yoga articulated in the Viṣṇu Purāṇa (fourth century CE) and argues that what seems like a unified teaching is a composite of an eight-limbed yoga embedded within an instruction on proto-Sāṃkhya. An evaluation of the key elements of yoga as developed in this text as a whole, clarifies our understanding of the emergence of yoga and its relationship to epic formulations on the one hand and to the Classical System of the Yogasūtras of Patañjali on the other.
