In the sacred teachings of the Chāndogya Upaniṣad, it is said that for those small creatures bound by ignorance, there is no path leading beyond; they are caught in a cycle, returning again and again, being born and dying—this is known as the third state of existence. Such a world remains unfulfilled, and thus, the wise are counseled to avoid it. Furthermore, it is taught that there are four grave sins: stealing gold, drinking liquor, violating the teacher’s wife, and murdering a Brahmin. One who associates with these sinners becomes the fifth. Yet, whoever truly understands the five sacred fires, even if he mingles with such people, remains unstained by sin. Pure and purified, he attains the world of merit—such is the power of true knowledge. In ancient times, there gathered together five illustrious householders, renowned for their learning: Prācīnaśāla Aupamanyava, Satyayajña Pauluṣa, Indradyumna Bhāllaveya, Jana Śārkarākṣya, and Buḍila Āśvatarāśvi. These wise men engaged in a profound discussion among themselves, pondering the deepest questions: “Who indeed is the Self? What is Brahman?” Seeking the highest understanding, they said to one another, “The revered Uddalaka, son of Aruna, is here; he has approached the knowledge of the Vaiśvānara Self. Let us go to him.” And so, they set out together to seek his guidance. Uddalaka, perceiving their approach, reflected, “These great householders and learned men will question me deeply. Perhaps I may not be able to answer all their inquiries. Therefore, I will have someone else instruct them.” He welcomed them and said, “Revered ones, Aśvapati, the king of the Kekayas, has also approached the Vaiśvānara Self. Let us go to him.” Together, they journeyed to Aśvapati. When they arrived, King Aśvapati received them with honor, preparing separate dwellings for each. In the morning, as he was about to depart, he addressed them, saying, “In my realm, there is no thief, no miser, no drunkard, no one who neglects the sacred fire, no ignorant person, no adulterer, nor adulteress—how then could there be one who sacrifices improperly? Revered ones, as long as I give wealth to each officiating priest, so long will I give to you. Please stay, revered ones.” But the assembled householders replied, “For the very purpose for which a man lives, let him speak in the same way. You have approached this Vaiśvānara Self; tell us about him alone.” The king agreed, saying, “At dawn, I will answer you.” So, with sacrificial fuel in hand, they approached him in the forenoon, and without further introduction, he began to speak. Turning to Aupamanyava, Aśvapati asked, “Whom do you meditate upon as your Self?” Aupamanyava replied, “Heaven itself, revered king.” The king said, “This radiant Self, the Vaiśvānara, is whom you meditate upon as your Self. Therefore, in your family, a radiant son is born. One who meditates thus eats food and sees what is dear, becomes dear, and his family shines with the radiance of Brahman. The head is this aspect of the Self. If you had not come to me, your head would have fallen.” He then questioned Satyayajña, son of Pauluṣa and Prācīnayogya, “Whom do you meditate upon as your Self?” Satyayajña answered, “The sun, revered king.” Aśvapati replied, “This is the all-formed Self, the Vaiśvānara, whom you meditate upon as your Self. Therefore, in your family, many with various forms are seen. One who meditates thus rides in a chariot drawn by mares, wears a golden necklace, eats food and sees what is dear, becomes dear, and his family shines with the radiance of Brahman. The eyes are this aspect of the Self. If you had not come to me, you would have become blind.” Next, he turned to Indradyumna Bhāllaveya and asked, “Whom do you meditate upon as your Self?” Indradyumna replied, “The wind, revered king.” The king said, “This is the Self with separate paths, the Vaiśvānara, whom you meditate upon as your Self. Therefore, separate strengths come to you, and separate lines of chariots follow you. One who meditates thus eats food and sees what is dear, becomes dear, and his family shines with the radiance of Brahman. The breath is this aspect of the Self. If you had not come to me, your breath would have departed.” He then addressed Jana Śārkarākṣya, “Whom do you meditate upon as your Self?” Jana replied, “Space itself, revered king.” The king answered, “This is the abundant Self, the Vaiśvānara, whom you meditate upon as your Self. Therefore, you are abundant in progeny and wealth. One who meditates thus eats food and sees what is dear, becomes dear, and his family shines with the radiance of Brahman. The cavity is this aspect of the Self. If you had not come to me, your cavity would have been destroyed.” To Buḍila Aśvatarāśvi, the king asked, “Whom do you meditate upon as your Self?” Buḍila replied, “Water itself, revered king.” The king said, “This is the wealthy Self, the Vaiśvānara, whom you meditate upon as your Self. Therefore, you are wealthy and prosperous. One who meditates thus eats food and sees what is dear, becomes dear, and his family shines with the radiance of Brahman. The bladder is this aspect of the Self. If you had not come to me, your bladder would have burst.” Finally, he turned to Uddālaka, son of Aruṇa, Gautama, and asked, “Whom do you meditate upon as your Self?” Uddālaka replied, “The earth itself, revered king.” The king said, “This is the foundation Self, the Vaiśvānara, whom you meditate upon as your Self. Therefore, you are established with progeny and cattle. One who meditates thus eats food and sees what is dear, becomes dear, and his family shines with the radiance of Brahman. These are the feet of the Self. If you had not come to me, your feet would have withered.” Aśvapati then addressed them all: “Indeed, you each meditate on the Vaiśvānara Self as if it were separate. But whoever worships the Vaiśvānara Self as measured by a span and as the true Self, he eats food in all worlds, among all beings, and in all selves. Of this Vaiśvānara Self, the head is the blazing fire, the eye is of manifold forms, the breath moves in different paths, the trunk is abundance, the bladder is wealth, the feet are the earth, the sides are the altar, the hairs are the sacred grass, the heart is the household fire, the mind is the offering fire, and the mouth is the fire of oblation.” He then taught them the proper way to offer food as oblation to the five vital breaths: “When the first portion of food is brought, offer it with the words, ‘To Prāṇa, svāhā.’ Prāṇa is satisfied; then the eye, the sun, the sky, and whatever is established in the sky and sun are satisfied. By this satisfaction, one is fulfilled with offspring, cattle, food, vigor, and the splendor of Brahman. “Next, offer to Vyāna, saying, ‘To Vyāna, svāhā.’ Vyāna is satisfied; then the ear, the moon, the directions, and whatever is established in the directions and moon are satisfied. Thus, one is fulfilled with offspring, cattle, food, vigor, and the splendor of Brahman. “Then, offer to Apāna, saying, ‘To Apāna, svāhā.’ Apāna is satisfied; then speech, fire, the earth, and whatever is established in the earth and fire are satisfied. Thus, one is fulfilled with offspring, cattle, food, vigor, and the splendor of Brahman. “Next, offer to Samāna, saying, ‘To Samāna, svāhā.’ Samāna is satisfied; then the mind, the rain god, lightning, and whatever is established in lightning and the rain god are satisfied. Thus, one is fulfilled with offspring, cattle, food, vigor, and the splendor of Brahman. “Finally, offer to Udāna, saying, ‘To Udāna, svāhā.’ Udāna is satisfied; then the skin, air, space, and whatever is established in air and space are satisfied. Thus, one is fulfilled with offspring, cattle, food, vigor, and the splendor of Brahman. “If someone, not knowing this, performs the Agnihotra sacrifice, it is as if he were to remove the coals and offer into ashes; such is the fruitless result. But if someone, knowing this, performs the Agnihotra, then his offering is made in all worlds, among all beings, and in all selves. Just as a tuft of cotton, thrown into the fire, is completely burned, so all sins are burned away for one who, knowing this, performs the Agnihotra. Therefore, even if such a knower were to give leftovers to a Chandāla, it would be as if it were offered in his own Vaiśvānara Self. Just as hungry children gather around their mother, so do all beings gather around the Agnihotra; thus, one should worship the Agnihotra.” And so, the teachings continued. In another time, there was Śvetaketu, the son of Aruṇa. His father said to him, “Śvetaketu, go and live the life of a student; for, dear one, in our family, none who is not learned in the Veda should be called merely a Brahmin by birth.” Thus, the search for true knowledge and realization ever continues.
