Acharya Prashant explains that the question of what is good or bad only arises as long as these concepts hold personal significance and value for an individual. He suggests that everyone already possesses a personal definition of good and bad, and the path to true understanding begins by examining these existing definitions rather than accumulating more external knowledge. He warns that adding more information without examining one's current beliefs only increases the mental burden and makes a person more artificial. True honesty lies in investigating and checking what one already claims to know.
