One is attached to the body and is afraid to lose it. Yet kayostsarg induce a death-like state in which all thoughts, feeling and desires vanish and the body lies still. Having faced death one remains no longer afraid of it. Thus through kayotsarg one can conquer the fear of death and thus rid oneself of the tension and oppressive feeling accompanying the fear. Here it is worth remembering that fear resides within and not outside us.
External fear is mere fiction.
If we succeed in cultivating fearlessness no incident, no external circumstances can strike fear in us. There is an incident related to Mahatma Gandhi's life. Once during one of his marches through the countryside he encountered a procession of people singing and dancing to the beats of a drum and carrying a goat for sacrificing in a temple dedicated to a goddess. Gandhiji walked ahead of them and sat down obstructing their way to the temple. The people asked him to get out of their way.
