CONTROL OVER MIND
Human excrement is totally useless; only swine eat it. Similarly, when the flesh is cut from a carcass, only bones remain and these are thrown to the dogs. Man's mind is like flesh, and his body is like the bones.
A person eats flesh [meat] and digests it, which means he uses it. But the bones are inedible and of no use; so he gives them to dogs, who can chew and utilize them.
A human being must care for his mind, which is like the meat. He should use his mind by training it to flow into the proper channels.
A person has to let go of his physical body sometime, for it cannot be preserved. To illustrate this: suppose one's finger is chopped off or a leg is crippled, he should not worry or weep over it because he knows that his whole physical body has to be discarded one day. But a human being should be most careful about his mind, which is of the utmost use to him. The mind should be directed toward proper spheres; it should be kept in check and utilized.
If this body, which a person has to discard one day, is used for anything, it should be used in the service of three causes: God, the Master and our fellowman. The body may become weary and worn-out — it may bring one suffering — but so what? Man, as a physical being, is destined to suffer. So long as the body is vibrant, active and under one's control, man can be said to have used it for a good cause by directing his energies in any good or noble work.
Everything depends on the mind. The mind feeds on happiness and misery. The world is really a dream. Happiness and sorrow are plays of the mind; there is no substance in either. In fact, the mind exists to endeavor to see God, but it leaves this aside and becomes caught up in the world. "I want this! I want that!" it shouts. The mind gets one entangled in maya and thereby increases desires. No sooner is one desire satisfied than another is there ready to be satisfied. Thus, one after another, desires increase without limit and they never bring freedom to anyone.
So the man who has control over the mind possesses the whole universe. He has no use for happiness, suffering, health, wealth or anything else. He is beyond all that.
