Acharya Prashant explains that confusion is a state of conflict and fragmentation within the mind, occurring when the brain is enslaved by multiple external influences such as family, media, religion, and society. He describes the brain as a battleground where these various external masters pull the individual in different directions. The tragedy of confusion is that even if one direction is chosen, it is never the individual's own path but rather an external one. He emphasizes that most people are caught in the illusion that these externally imposed choices are their own.
