There are more fake gurus and false teachers in this world than the number of stars in the visible universe. Don't confuse power-driven, self-centered people with true mentors. A genuine spiritual master will not direct your attention to himself or herself and will not expect absolute obedience or utter admiration from you, but instead will help you to appreciate and admire your inner self. True mentors are as transparent as glass. They let the Light of God pass through them.
