"Psychologists are of opinion that there cannot be absolute fearlessness and that only determined effort can be made to conquer fear. This is incorrect. Psychologists have no transcendental experience. A perfect sage who has knowledge of Brahman is absolutely fearless. Upanishads declare in a thundering voice, “The knower of the fearless Brahman becomes himself absolutely fearless.” (Brihadaranyakopanishad)"
