Listen, O seeker, to this sacred tale from the ancient wisdom of the Upanishad, where the great sage Yājñavalkya imparts the highest knowledge to Maitreyi. The form of the supreme person, Yājñavalkya reveals, is wondrous to behold—like a garment fit for royalty, pure as a white woolen cloth, radiant as a firefly, a blazing flame, a blossoming lotus, or the sudden brilliance of lightning. Indeed, his radiance is as a flash of lightning—such is the glory known to one who truly understands. But to know this, one must follow the instruction: “Not this, not this”—neti, neti. For there is nothing higher than this negation; all attempts to define the ultimate fall short. Its true name is the “Truth of truth.” The breath is truth, and among all these, this is the highest truth. Now, as the time of departure drew near, Yājñavalkya addressed Maitreyi, “Maitreyi, I am about to leave this place. Come, let me make the final arrangements for you and for Katyayani.” But Maitreyi, wise and discerning, asked, “O revered one, if the whole earth were filled with wealth, could I attain immortality by that?” Yājñavalkya replied, “As is the life of those who have possessions, so would be your life. But through wealth, there is no hope of immortality.” Maitreyi persisted, “That which cannot grant me immortality—what use have I for it? Whatever you know, O revered one, that alone please teach me.” Yājñavalkya, pleased by her earnestness, said, “You have spoken dear words, as one who is truly dear. Come, sit down. I shall explain to you. But as I teach, you must contemplate deeply.” “Speak, O revered one,” replied Maitreyi. Yājñavalkya then began to unfold the connection, the very Upanishad, the deep teaching of the Brihadaranyaka Upanishad, moving from one section to the next, opening the way to the heart of knowledge. He said, “Whoever knows Brahman as something separate from the Self, to him Brahman is lost. Whoever knows power, or the worlds, or the gods, or beings, or all things as separate from the Self—to him, all these are lost. For this—this very Self—is Brahman, is power, is the worlds, is the gods, is the beings, is all. All is the Self.” He illustrated with examples: “Just as, when a drum is struck, you cannot catch the sound apart from the drum and the striking, but by grasping the drum or the act, you catch the sound—so too with the Self and all things. Or as, when a lute is played, you cannot catch the music apart from the lute and the playing; or when a conch is blown, you cannot grasp the sound apart from the conch and the blowing—so it is with all things arising from the Self.” He continued, “Just as, when a fire is kindled with damp fuel, various smokes arise, so too from this great being, the breathings arise: the Rigveda, Yajurveda, Samaveda, Atharvangirasa, history, ancient lore, knowledge, Upanishads, verses, aphorisms, explanations, commentaries—all these are the breath of that great being.” He explained the unity of all things: “As all waters flow to the ocean, as all touches are resolved in the skin, all smells in the nose, all tastes in the tongue, all forms in the eye, all sounds in the ear, all intentions in the mind, all Vedas in speech, all actions in the hands, all movements in the feet, all pleasures in the generative organ, all excretions in the anus, and all knowledges in the heart—so too, all things merge in the Self.” He offered another image: “When a lump of salt is thrown into water, it dissolves, becoming indistinguishable; wherever you taste, it is salty. In the same way, this great, endless, infinite, full mass of knowledge arises from these elements and merges back into them. After death, there is no separate consciousness—so I say,” declared Yājñavalkya. At this, Maitreyi was troubled. “O revered one, you have thoroughly confused me by saying that after death there is no distinct consciousness.” Yājñavalkya reassured her, “No, dear, I do not speak confusion. This is enough for understanding.” He explained further, “Where there is duality, one sees another, one smells another, one hears another, one speaks to another, one thinks of another, one knows another. But when everything has become just one’s own Self, then by what means and whom would one see? By what means and whom would one smell, hear, speak to, think of, or know? By what means could one know the knower? That by which all this is known—how could one know that knower?” Yājñavalkya then declared the oneness of the Self with all creation. “This earth is the honey of all beings, and all beings are the honey of this earth. The luminous, immortal person who is in the earth and who is in the body—he is the Self, this immortal, this is Brahman, this is all. The same is true of the waters, the fire, the space, the air, the sun, the moon, the directions, the lightning, the thunder, righteousness, truth, human beings, and finally the Self itself. In each, the luminous, immortal person who dwells within is the same Self, the immortal, Brahman, the all.” He continued, “This Self is the lord and king of all beings. Just as the spokes are fixed in the hub and rim of a wheel, so too, in this Self, all beings, all gods, all worlds, all breaths, all selves are fixed.” He recalled the ancient transmission of this wisdom: “This is that honey, that secret teaching, which Dadhyanc Atharvana spoke to the Ashvins. The seers, seeing this, spoke in the Rig Veda: ‘For you, O men, I make manifest a mighty, formidable thing for gaining wealth, like the thunderer his rain; for Dadhyanc Atharvana spoke to you the honey by means of the horse’s head.’ And again: ‘For Atharvana, O Ashvins, you replaced the head of Dadhyanc with that of a horse; he then spoke to you the honey, the true Tvastri’s secret, O wondrous ones, which was hidden in the armpit.’” He described the Self’s all-pervading nature: “He made the bipeds and quadrupeds, and, having become a bird, entered in front as a person. Thus, this person is present in all bodies, in every dwelling; nothing is uncovered by him, nothing is covered from him. He became the likeness of every form; that is his form for each to see—Indra, by his powers, moves in many forms, for his horses are yoked by the hundreds and tens. These are indeed the horses, the tens, the thousands, and countless others. This is that Brahman—without a before, without an after, without an inside, without an outside. This Self is Brahman, the all-pervading. Thus is the teaching.” And as is the tradition, Yājñavalkya recounted the lineage through which this wisdom was transmitted, from teacher to disciple, generation after generation, reaching back to the self-born Brahman. “Salutation to Brahman,” he concluded. Thus ends the sacred teaching, a stream of wisdom flowing from the ancient seers, revealing the unity of all existence in the Self, the immortal, the all—Brahman.
