Because an illumined soul experiences the nondual Brahman, he can never fear anyone. - Ramakrishna.

Vedanta says that a knower of Brahman becomes fearless. Fear originates from duality. Because an illumined soul experiences the nondual Brahman, he can never fear anyone.
Once while in the Himalayan region in Tihiri-Garhwal, Swami Turiyananda was living in a thatched hut that had a broken door. One night he heard the villagers cry, "Tiger! Tiger!" He immediately put some bricks behind the door to protect himself. Just then he remembered a passage from the Taittiriya Upanishad that declares that even at the command of Brahman the god of death does his duty like a slave. His awareness of the Atman awakened, and defeated the body idea. He kicked the piles of brick away from the entrance, and sat for meditation." Fortunately, the tiger did not show up.
