Acharya Prashant explains that intelligence is not a skill or the ability to solve problems quickly; rather, it is the state of being quiet and doing nothing. He clarifies that while repetition and experience can increase speed in tasks like mathematics, true understanding arises from a state of inner silence and oneness with the subject. He illustrates this by suggesting that one can perceive things previously unnoticed, such as the beauty of nature, simply by standing still and observing without mental noise. He emphasizes that intelligence is a natural blessing that awakens when the mind stops its constant activity.
