Puruṣa originally meant the cosmic person of the Vedic hymns. In Sāṃkhya and Yoga it is pure consciousness, many in number, which witnesses but never acts or changes; all activity belongs to matter. Bondage is the confusion of puruṣa with the workings of matter, and liberation is their discrimination.
