Acharya Prashant explains that identifying oneself with the body is the root cause of all bondage and fear. If one believes they are the body, life becomes a mere journey from birth to death, and every action is driven by the fear of mortality. This identification turns the world into a graveyard where one constantly seeks security through social recognition, family milestones, and material accumulation. He asserts that death is not a physical state but a psychological illusion born from the ego's limited definition of life. By defining life only as bodily activities like breathing and walking, one inadvertently invites the concept of death for everything that does not perform these actions.
