The Yoga School Restores an Ishvara Samkhya Leaves Out

The Yoga school built by Patanjali's Yoga Sutras shares Samkhya's analysis of purusha and prakriti almost point for point, yet adds a single figure Samkhya has no place for. Edwin Bryant's edition and commentary on the Yoga Sutras traces how the text names Ishvara, God, as a purusha vishesha, a distinguished or special instance of consciousness untouched by the afflictions, actions and their fruits that bind every ordinary purusha, offered to the practitioner as an optional aid to concentration rather than installed as the world's creator or first cause. Because Yoga otherwise keeps Samkhya's account of an uncaused, self-unfolding prakriti, Ishvara has no cosmological work to do in this system either, only a devotional and meditative one, which is why later interpreters have called classical Yoga seshvara Samkhya, Samkhya with a God attached, rather than a genuinely rival cosmology. Bryant's commentary notes that later Samkhya adjacent thinkers, Vijnanabhikshu among them, worked to harmonize the two schools' theism and atheism into a single reading, a sign that the difference was felt as a real tension rather than a settled non-issue. Classical Samkhya itself did not survive as an independent living school much past the medieval period, its analysis absorbed piecemeal into later Vedanta and into Yoga rather than continuing as a separate sect with its own institutions.
