O Agni (Bright Being)! Lead us to blessedness by the good path. O Lord! Thou knowest all our deeds, remove all evil and delusion from us. To Thee we offer our prostrations and supplications again and again. Here ends this Upanishad This Upanishad is called Isa-Vasya-Upanishad, that which gives Brahma-Vidya or knowledge of the All-pervading Deity. The dominant thought running through it is that we cannot enjoy life or realize true happiness unless we consciously "cover" all with the Omnipresent Lord. If we are not fully conscious of that which sustains our life, how can we live wisely and perform our duties? Whatever we see, movable or immovable, good or bad, it is all "That." We must not divide our conception of the universe; for in dividing it, we have only fragmentary knowledge and we thus limit ourselves. He who sees all beings in his Self and his Self in all beings, he never suffers; because when he sees all creatures within his true Self, then jealousy, grief and hatred vanish. He alone can love. That AH-pervading One is self- effulgent, birthless, deathless, pure, untainted by sin and sorrow. Knowing this, he becomes free from the bondage of matter and transcends death. Transcending death means realizing the difference between body and Soul and identifying oneself with the Soul. When we actually behold the undecaying Soul within us and realize our true nature, we no longer identify ourself with the body which dies and we do not die with the body. Self-knowledge has always been the theme of the Sages; and the Upanishads deal especially with the knowledge of the Self and also with the knowledge of God, because there is no difference between the Self and God. They are one and the same. That which comes out of the Infinite Whole must also be infinite; hence the Self is infinite. That is the ocean, we are the drops. So long as the drop remains separate from the ocean, it is small and weak; but when it is one with the ocean, then it has all the strength of the ocean. Similarly, so long as man believes himself to be separate from the Whole, he is helpless; but when he identifies himself with It, then he transcends all weakness and partakes of Its omnipotent qualities. Katha-Upanishad The Katha-Upanishad is probably the most widely known of all the Upanishads. It was early translated into Persian and through this rendering first made its way into Europe. Later Raja Ram Mohun Roy brought out an English version. It has since appeared in various languages; and English, German and French writers are all agreed in pronouncing it one of the most perfect expressions of the religion and philosophy of the Vedas. Sir Edwin Arnold popularized it by his metrical rendering under the name of "The Secret of Death," and Ralph Waldo Emerson gives its story in brief at the close of his essay on "Immortality."
