Acharya Prashant explains that true understanding does not come from interpretation, as interpretation is inherently flawed and leads to persistent suspicion and doubt. He suggests that sitting quietly without judging one's own level of understanding is an act of faith, whereas constant checking and analyzing is a sign of suspicion. He notes that students often progress from doubting the teacher to doubting themselves, but both stages are rooted in the mind's attempt to solve a puzzle rather than experiencing true companionship.
