Acharya Prashant explains that the concepts of introversion and extroversion are modern psychological terms that have no real place in spirituality or Vedanta. Psychology often views these as distinct traits because it operates from a body-centric perspective, whereas Vedanta sees both as forms of attachment to the 'other.' Whether one is talking to people outside or engaging in internal dialogue with their own thoughts, both are considered interactions with something other than the true Self. He emphasizes that being alone with one's thoughts is not necessarily superior to being in a crowd, as the same worldly influences and 'crowds' exist within the mind as memories and ideas.
