Acharya Prashant discusses the psychological tendency to believe in supernatural phenomena like spirit possession as a means to avoid personal responsibility. He recounts an interaction with a well-educated individual who claimed to be possessed by a mean spirit that attacked her during moments of happiness, citing YouTube videos as proof of such occurrences. He explains that the ego is deeply afraid of responsibility, which is synonymous with truth. By believing in hidden masters, invisible forces, or possession, individuals console themselves and avoid taking charge of their own lives. This belief system serves as a convenient excuse for personal failures, such as failing an exam, by attributing outcomes to external, uncontrollable entities rather than one's own actions.
