Acharya Prashant explains that intellectual knowledge gained from books and listening is often just memory and ideas rather than true realization. He emphasizes that one must recognize when a thought or concept has entered from the outside. True awareness or 'Bodha' is not speaking from memory after an event has occurred, but being present with the event itself. He clarifies that what is truly gained is not obtained through thought; if something is acquired via thought, it holds no real value. When one experiences a state of 'not knowing' or silence, they should remain in it without trying to intellectualize it, as the peace found there stems from that very lack of conceptual knowledge.
