Acharya Prashant describes the inherent cruelty and helplessness of being a teacher, characterizing it as a state of knowing everything while possessing very little power to act on behalf of others. He explains that while a teacher can identify a path of destruction and warn a student, the admission and the subsequent action must come from the individual. Life cannot be outsourced, and just as a coach cannot play for a player, a teacher cannot live or make choices for their students. This creates an extremely frustrating experience where one witnesses self-destructive behavior but lacks the power to forcefully intervene.
