Acharya Prashant explains that the mind chatters because it is engaged with petty and inconsequential matters. He describes the mind as a monkey that needs something to play with; if it is not given a significant task, it begins to play with itself, which leads to suffering. He compares a chattering mind to a car engine revving in neutral at high RPMs; it generates noise and heat and burns fuel without covering any distance. This internal conversation is a dissipation of precious life energy and represents a dangerous way to exist. To stop this chatter, one must give the mind a solemn and constructive purpose. He notes that because people are often lazy, they prefer to let the mind work in isolation while the body remains inactive. He emphasizes that the only way to prevent the mind from becoming destructive is to channelize one's entire existence and body toward a right and purposeful goal.
