Acharya Prashant clarifies the distinction between the terminologies of Sankhya and Vedanta. In Sankhya, 'Purush' refers to a vulnerable, sentient consciousness or mind that is often corrupted by and identified with 'Prakriti' (nature/the world), necessitating a search for redemption. In contrast, Vedanta defines 'Purush' as the pure self or Atma, which is the state attained after gaining liberation from worldly identification. He explains that the mind and body are essentially one, with the body being the gross form of the mind. True liberation involves the small, dualistic self merging into the non-dual pure self, which is the only reality.
