Acharya Prashant explains that the only mantra for fearlessness is to view life as a game where gains and losses do not affect one's true nature. He emphasizes that whether one receives wealth, honor, or insults, one's essential self remains unchanged and nothing can be taken away from what truly belongs to the individual. He points out that fear is a result of living in constant hope and greed for external validation and acquisitions, as anything that can be gained can also be lost. Acharya Prashant asserts that fear is not an uninvited guest but is invited by one's own attachments, greed, and expectations. He encourages playing the game of life with full strength and the intent to win, yet remaining indifferent to the final outcome. By letting go of these invitations to fear, such as greed and attachment, one can live a life where fear simply ceases to exist rather than being suppressed or fought.
