The mind clings to some thing or other; make it cling to God. The mind is like a mad monkey, while the body is like a water bubble which may burst at any moment. Therefore, you must follow only the conscience. You cannot realize your divinity as long as your mind is filled with evil thoughts.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
