Though sitting, It travels far; though lying, It goes everywhere. Who else save me is fit to know that God, who is (both) joyful and joyless? The Self is all-pervading, hence It is that which sits still and that which travels, that which is active and that which is inactive. It is both stationary and moving, and It is the basis of all forms of existence; therefore whatever exists in the universe, whether joy or joylessness, pleasure or pain, must spring from It. Who is better able to know God than I myself, since He resides in my heart and is the very essence of my being? Such should be the attitude of one who is seeking. XXII The wise who know the Self, bodiless, seated within perishable bodies, great and all- pervading, grieve not. Then a wise man through the practice of discrimination has seen clearly the distinction between body and Soul, he knows that his true Self is not the body, though It dwells in the body. Thus realizing the indestructible, all-pervading nature of his real Self, he surmounts all fear of death or loss, and is not moved even by the greatest sorrow. XXIII This Self cannot be attained by study of the Scriptures, nor by intellectual perception, nor by frequent hearing (of It); He whom the Self chooses, by him alone is It attained. To him the Self reveals Its true nature. We may imagine that by much study we can find out God; but merely hearing about a thing and gaining an intellectual comprehension of it does not mean attaining true knowledge of it. Knowledge only comes through direct perception, and direct perception of God is possible for those alone who are pure in heart and spiritually awakened. Although He is alike to all beings and His mercy is on all, yet the impure and worldy-minded do not get the blessing, because they do not know how to open their hearts to it. He who longs for God, him the Lord chooses; because to him alone can He reveal His true nature. XXIV 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. A 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. XXV Who then can know where is this mighty Self? He (that Self) to whom the Brahmanas and Kshatriyas are but food and death itself a condiment.
