Acharya Prashant explains that the inquiry into one's identity is not a thought-based process or a typical question requiring a verbal answer. He clarifies that asking who one is should be a subtle realization of how one is currently acting, rather than a mental effort or introspection. He emphasizes that pure awareness and bliss are not feelings or mental activities; if one is still feeling something, it remains within the realm of the mind. He further notes that one cannot try to be a witness because witnessing is one's inherent nature; one is already the witness of the very effort to try.
