Upanishad and Yogatattva Upanishad, because they make frequent references to it. Yoga Yajnavalkya versus Patanjali's Yogasutra The philosophical premises of Yajnavalkya and Patanjali are different, according to Richard Rosen. Patanjali accepts the dualism premise, and defines yoga as cessation of mental activity associated with sensory interaction with nature, leading to Kaivalya (aloneness) of the self and a state of self-awareness. Yajnavalkya accepts the Advaita Vedanta premise of non-dualism, "essential oneness of self and nature", and defines yoga as path to intense interconnectedness between Jiva and Paramatman, where the union of self and supreme self is realized.
