Acharya Prashant addresses the common problem of unwanted mental noise, which he identifies as a manifestation of fear and doubt. He explains that this noise arises when the mind is not present in the current moment but is instead wandering into the past or future. This mental chatter is a sign of being decoupled from the immediate reality of life. He observes that when one is deeply immersed in an activity, such as playing a sport or listening attentively, the noise naturally falls silent because the mind is anchored in the present.
