Acharya Prashant explains that fear is a fundamental instinct that arises from a distance from the truth. A person who is afraid constantly tries to protect themselves and can be dangerous because they are disconnected from reality. To maintain this distance from the truth, the mind uses various excuses, one of which is hesitation or doubt. People often wait for absolute certainty before taking a step toward the truth, but Acharya Prashant clarifies that in the human condition, clarity can never be one hundred percent. Waiting for total certainty is merely a conspiracy of the mind to remain stuck in its current state. He encourages taking the first step based on the best available understanding and honesty, as the next step only becomes clear once the first is taken.
