A SURE AID
There is no doubt that Rama Nama is the surest aid. If recited from the heart, it charms away every evil thought; and evil thought gone, no corresponding action is possible.
The outward helps are all useless if the mind is weak. They are superfluous if the mind is pure. This must not be taken to mean that a pure-minded man can take all the liberties and still keep safe. Such a man simply will not take any liberties with himself. His whole life will be an infallible testimony to the inward purity. The Gita truly says that mind makes the man and unmakes him. Milton paraphrases the same thought when he says: "The mind in its own place, and in itself can make a Heaven of Hell, a Hell of Heaven."
