What is purusa?

Purusha is a concept in Indian philosophy, particularly in the context of Hinduism and Samkhya, representing the cosmic spirit or consciousness. It is often contrasted with Prakriti, the material world or nature, indicating a dualistic understanding of existence. Purusha embodies the eternal, unchanging essence of the self or soul, transcending physical form and individuality. This idea is central to understanding the relationship between the individual self and the universe.
