This verse highlights that the Atman is not a subject for intellectual mastery. It cannot be reached through scholarly lectures, sharp intelligence, or extensive listening to scriptures. Rather, the Atman reveals its true nature only to the seeker who longs for it with a sincere and dedicated heart.
