I know that (earthly) treasure is transitory, for the eternal can never be attained by things which are non-eternal. Hence the Nachiketa fire (sacrifice) has been performed by me with perishable things and yet I have attained the eternal.
O Nachiketas, thou hast seen the fulfillment of all desires, the basis of the universe, the endless fruit of sacrificial rites, the other shore where there is no fear, that which is praiseworthy, the great and wide support; yet, being wise, thou hast rejected all with firm resolve.
The teacher, saying that the imperishable cannot be attained by the perishable, shows that no amount of observance of rituals and ceremonies can earn the imperishable and eternal. Although the Nachiketa fire-sacrifice may bring results which seem eternal to mortals because of their long duration, yet they too must come to an end; therefore this sacrifice cannot lead to the final goal. Yama praises Nachiketas because, when all heavenly and earthly pleasures, as well as knowledge of all realms and their enjoyments were offered him, yet he cast them aside and remained firm in his desire for Truth alone.

The wise, who by means of the highest meditation on the Self knows the Ancient One, difficult to perceive, seated in the innermost recess, hidden in the cave of the heart, dwelling in the depth of inner being, (he who knows that One) as God, is liberated from the fetters of joy and sorrow.
XIII
A mortal, having heard and fully grasped this, and having realized through discrimination the subtle Self, rejoices, because he has obtained that which is the source of all joy. I think the abode (of Truth) is open to Nachiketas.
The Scriptures give three stages in all spiritual attainment. The aspirant must first hear about the Truth from an enlightened teacher; next he must reflect upon what he has heard; then by constant practice of discrimination and meditation he realizes it; and with realization comes the fulfilment of every desire, because it unites him with the source of all. Having beheld this, a man learns that all sense pleasures are but fragmentary reflections of that one supreme joy, which can be found in the true Self alone. Yama assures Nachiketas that there is no doubt of his realizing the Truth, because he has shown the highest discrimination as well as fixity of purpose.
XIV
Nachiketas said: That which thou seest, which is neither virtue nor vice, neither cause nor effect, neither past nor future (but beyond these), tell me That.
Yama replied: That goal which all the Vedas glorify, which all austerities proclaim, desiring which (people) practice Brahmacharya (a life of continence and service), that goal I tell thee briefly--it is Aum.
What name can man give to God? How can the Infinite be bound by any finite word? All that language can express must be finite, since it is itself finite. Yet it is very difficult for mortals to think or speak of anything without calling it by a definite name. Knowing this, the Sages gave to the Supreme the name A-U-M which stands as the root of all language. The first letter "A" is the mother-sound, being the natural sound uttered by every creature when the throat is opened, and no sound can be made without opening the throat. The last letter "M," spoken by closing the lips, terminates all articulation. As one carries the sound from the throat to the lips, it passes through the sound "U." These three sounds therefore cover the whole field of possible articulate sound. Their combination is called the Akshara or the imperishable word, the Sound-Brahman or the Word God, because it is the most universal name which can be given to the Supreme. Hence it must be the word which was "in the beginning" and corresponds to the Logos of Christian theology. It is because of the all-embracing significance of this name that it is used so universally in the Vedic Scriptures to designate the Absolute.

This Word is indeed Brahman. This Word is indeed the Supreme. He who knows this Word obtains whatever he desires.
XVII
This is the best Support, This is the highest Support; he who knows this Support is glorified in the world of Brahman.
This sacred Word is the highest symbol of the Absolute. He who through meditating on It grasps Its full significance, realizes the glory of God and at once has all his desires satisfied, because God is the fulfilment of all desires.
XVIII
This Self is never born, nor does It die. It did not spring from anything, nor did anything spring from It. This Ancient One is unborn, eternal, everlasting. It is not slain even though the body is slain.
XIX
If the slayer thinks that he slays, or if the slain thinks that he is slain, both of these know not. For It neither slays nor is It slain.
The Self is subtler than the subtle, greater than the great; It dwells in the heart of each living being. He who is free from desire and free from grief, with mind and senses tranquil, beholds the glory of the Atman.
Although this Atman dwells in the heart of every living being, yet It is not perceived by ordinary mortals because of Its subtlety. It cannot be perceived by the senses; a finer spiritual sight is required. The heart must be pure and freed from every unworthy selfish desire; the thought must be indrawn from all external objects; mind and body must be under control; when the whole being thus becomes calm and serene, then it is possible to perceive that effulgent Atman. It is subtler than the subtle, because It is the invisible essence of every thing; and It is greater than the great because It is the boundless, sustaining power of the whole universe; that upon which all existence rests.
XXI
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.
