Acharya Prashant explains that a teacher's words do not create new sadness but rather expose the preexisting sadness that an individual has suppressed. He notes that suppression only makes sadness more powerful and that the teacher's role is to demonstrate both the reality of one's sadness and its lack of necessity. He addresses the common complaint that a teacher makes people unhappy, clarifying that the teacher merely acts as a mirror to show how unhappy a person already is, even behind their smiles. He argues that suppression is ineffective because the underlying issue remains, as evidenced by the defensive actions people take, such as seeking constant entertainment or noise to hide from their internal state. He concludes that just as carrying a gun proves one believes in an enemy, these defensive behaviors prove the existence of the very sadness one tries to ignore, and that true resolution comes from realizing the 'enemy' or sadness is unnecessary rather than trying to hide from it.
