Purusha

Purusha (Sanskrit: पुरुष, IAST: Puruṣa) is a complex concept whose meaning evolved in Vedic and Upanishadic times. Depending on source and historical timeline, it means the cosmic man or it means Self, Consciousness, and Universal principle. In early Vedas, Purusa meant a cosmic man whose sacrifice by the gods created all life. This was one of many creation theories discussed in the Vedas. The idea parallels Norse Ymir, with the myth's origin in Proto-Indo-European religion.
