Acharya Prashant explains that fear is a fundamental human instinct rooted in the constant anxiety of losing something or being diminished. He states that fear persists as long as one feels they are in a dangerous, unknown world where their possessions, status, or life can be snatched away. This fear is essentially the fear of becoming 'less' or being destroyed. He emphasizes that true fearlessness is only possible when one realizes that their core self is indestructible and that they are always at home in existence. Until this deep conviction is established—that nothing can truly be harmed—excuses for fear will always remain. He further elaborates that we actively invite fear by filling our lives with things that can be lost, such as reputation, wealth, and attachments to people. Since these are external and dependent on others, the threat of their loss creates constant insecurity. Acharya Prashant suggests that the only mantra for fearlessness is to view life as a play where gains and losses do not change one's essential nature. He advises living without being bound by hope or greed for results, as those who live in hope are destined to live in fear. By dropping attachments and the greed for external validation, one stops inviting fear, making life a joyful game where neither victory nor defeat affects one's inner state.
