“You have understood that the man who lives in ignorance and enjoys, is not different from the brute beast. Yet there are many who, though steeped in ignorance, in the pride of their hearts, think that they are great sages and go round and round in many crooked ways, like the blind led by the blind. This truth, Nachiketas, never shines in the heart of those who are like ignorant children, deluded by a few lumps of earth. They do not understand this world, nor the other world. They deny this and the other one, and thus again and again come under my control. Many have not even the opportunity to hear about it; and many, though hearing, cannot know it, because the teacher must be wonderful; so must he be wonderful too unto whom the knowledge is carried. If the speaker is a man who is not highly advanced, then even a hundred times heard, and a hundred times taught, the truth never illumines the soul. Do not disturb your mind by vain arguments, Nachiketas; this truth only becomes effulgent in the heart which has been made pure. He who cannot be seen without the greatest difficulty, He who is hidden, He who has entered the cave of the heart of hearts — the Ancient One — cannot be seen with the external eyes; seeing Him with the eyes of the soul, one gives up both pleasure and pain. He who knows this secret gives up all his vain desires, and attains this superfine perception, and thus becomes ever blessed. Nachiketas, that is the way to blessedness. He is beyond all virtue, beyond all vice, beyond all duties, beyond all non-duties, beyond all existence, beyond all that is to be; he who knows this, alone knows. He whom all the Vedas seek, to see whom men undergo all sorts of asceticism, I will tell you His name: It is Om. This eternal Om is the Brahman, this is the immortal One; he who knows the secret of this — whatever he desires is his. This Self of man, Nachiketas, about which you seek to know, is never born, and never dies. Without beginning, ever existing, this Ancient One is not destroyed, when the body is destroyed. If the slayer thinks that he can slay, and if the slain man thinks he is slain, both are mistaken, for neither can the Self kill, nor can It be killed. Infinitely smaller than the smallest particle, infinitely greater than the greatest existence, the Lord of all lives in the cave of the heart of every being. He who has become sinless sees Him in all His glory, through the mercy of the same Lord. (We find that the mercy of God is one of the causes of God-realisation.) Sitting He goes far, lying He goes everywhere; who else but men of purified and subtle understanding are qualified to know the God in whom all conflicting attributes meet? Without body, yet living in the body, untouched, yet seemingly in contact, omnipresent — knowing the Âtman to be such, the sage gives up all misery. This Atman is not to be attained by the study of the Vedas, nor by the highest intellect, nor by much learning. Whom the Atman seeks, he gets the Atman; unto him He discloses His glory. He who is continuously doing evil deeds, he whose mind is not calm, he who cannot meditates he who is always disturbed and fickle — he cannot understand and realise this Atman who has entered the cave of the heart. This body, O Nachiketas, is the chariot, the organs of the senses are the horses, the mind is the reins, the intellect is the charioteer, and the soul is the rider in the chariot. When the soul joins himself with the charioteer, Buddhi or intellect, and then through it with the mind, the reins, and through it again with the organs, the horses, he is said to be the enjoyer; he perceives, he works, he acts. He whose mind is not under control, and who has no discrimination, his senses are not controllable like vicious horses in the hands of a driver. But he who has discrimination, whose mind is controlled, his organs are always controllable like good horses in the hands of a driver. He who has discrimination, whose mind is always in the way to understand truth, who is always pure — he receives that truth, attaining which there is no rebirth. This, O Nachiketas, is very difficult, the way is long, and it is hard to attain. It is only those who have attained the finest perception that can see it, that can understand it. Yet do not be frightened. Awake, be up and doing. Do not stop till you have reached the goal. For the sages say that the task is very difficult, like walking on the edge of a razor. He who is beyond the senses, beyond all touch, beyond all form, beyond all taste, the Unchangeable, the Infinite, beyond even intelligence, the Indestructible — knowing Him alone, we are safe from the jaws of death.”
So far, we see that Yama describes the goal that is to be attained. The first idea that we get is that birth, death, misery, and the various tossings about to which we are subject in the world can only be overcome by knowing that which is real. What is real? That which never changes, the Self of man, the Self behind the universe. Then, again, it is said that it is very difficult to know Him. Knowing does not mean simply intellectual assent, it means realisation. Again and again we have read that this Self is to be seen, to be perceived. We cannot see it with the eyes; the perception for it has to become superfine. It is gross perception by which the walls and books are perceived, but the perception to discern the truth has to be made very fine, and that is the whole secret of this knowledge. Then Yama says that one must be very pure. That is the way to making the perception superfine; and then he goes on to tell us other ways. That self-existent One is far removed from the organs. The organs or instruments see outwards, but the self-existing One, the Self, is seen inwards. You must remember the qualification that is required: the desire to know this Self by turning the eyes inwards. All these beautiful things that we see in nature are very good, but that is not the way to see God. We must learn how to turn the eyes inwards. The eagerness of the eyes to see outwards should be restricted. When you walk in a busy street, it is difficult to hear the man speak with whom you are walking, because of the noise of the passing carriages. He cannot hear you because there is so much noise. The mind is going outwards, and you cannot hear the man who is next to you. In the same way, this world around us is making such a noise that it draws the mind outwards. How can we see the Self? This going outwards must be stopped. That is what is meant by turning the eyes inwards, and then alone the glory of the Lord within will be seen.
What is this Self? We have seen that It is even beyond the intellect. We learn from the same Upanishad that this Self is eternal and omnipresent, that you and I and all of us are omnipresent beings, and that the Self is changeless. Now this omnipresent Being can be only one. There cannot be two beings who are equally omnipresent — how could that be? There cannot be two beings who are infinite, and the result is, there
