He who has not turned away from evil conduct, whose senses are uncontrolled, who is not tranquil, whose mind is not at rest, he can never attain this Atman even by knowledge.
Yama having first described what the Atman is, now tells us how to attain It. Man must try to subdue his lower nature and gain control over the body and senses. He must conquer the impure selfish desires which now disturb the serenity of his mind, that it may grow calm and peaceful. In other words, he
must live the life and develop all spiritual qualities in order to perceive the Atman.
