What is man? Is not his soul divine substance? The very word man is from the Sanskrit Manu, which means mind. Man is what his mind is, what he thinks. "As a man thinketh in his heart, so he is." Even the future, as well as the past, is what he thinks, because he himself becomes the image of his thoughts. God created man in the image of his thoughts. If there is any self of which one can say, "This is man", it is the mind. The three Sanskrit words Mana, Manu, Manusha show that man is his mind, is the product of his mind, and is also the controller of the activity of mind. If he does not control his mind, he is not a master but a slave. It lies with his own mind whether he shall be master, or whether he shall be slave. He is slave when he neglects to be master; he is master if he cares to be master.
