Let us listen to the ancient wisdom as it unfolds, step by step, in the sacred narrative of the Kauṣītaki Upaniṣad. The journey begins with the mystery of the highest attainment. Once, all the deities that reside within the human body—each vying for supremacy—departed from the body, leaving it as if lifeless. One by one, they re-entered: first Speech, which enabled the person to speak, yet the body remained lifeless. Then Sight entered, granting vision, but still, life did not return. Hearing followed, bringing the power to hear, but the body was yet unmoved. The Mind entered, bringing thought, but life was absent. Finally, Breath entered—and at that, the person arose. The gods realized that Breath was the highest, the very self of wisdom. They united with Breath and, together, departed from this world, having wind as their foundation and space as their essence, thus attaining heaven. So too, one who knows this truth, uniting with Breath as the self of wisdom, departs from this body with all beings, and, having wind as foundation and space as essence, attains heaven. When the gods reach this, they become immortal; thus, the gods are immortal. Next, the transmission from father to son is described—a sacred rite. The father, preparing to pass on his spiritual essence, sends forth his son. He spreads nine blades of grass, establishes the fire, sets a water pot with a vessel, covers himself with a worn garment, and lies down. The son approaches, sits near, and, touching his senses to those of his father, faces him. The father then imparts each sense and faculty—speech, breath, sight, hearing, mind, the essence of food, actions, pleasure and pain, bliss and offspring, movement, intelligence, discernment, and desires—each time the son receiving and affirming, “Father, place this in me.” After the transmission, the father rises to the east, blessing his son with fame, radiance, nourishment, and glory. The son covers his right thigh, praying for heavenly worlds and fulfillment of desires. If the father remains healthy, he stays to witness his son’s prosperity, or he departs; if the son departs, the father completes the rite as prescribed. The tale then turns to Pratardana, son of Divodāsa, who approached Indra’s beloved realm through his prowess in battle. Indra, pleased, offered him a boon. Pratardana asked Indra to choose what was most beneficial for a human, but Indra insisted he choose himself. Pratardana then asked for immortality. Indra, who is approached through truth, replied: “Know me—this is what I consider most beneficial for a human: to know me.” Indra recounted his own victories over formidable demons and enemies, emerging unscathed. He declared, “Whoever knows me, no action destroys him—not by any sin or wrongdoing. Such a person is untouched by evil.” Indra then revealed: “I am Breath, the self of wisdom. Worship me as life and immortality. Breath alone is immortality; as long as Breath dwells in the body, there is life. Through Breath, one attains immortality in the next world; through wisdom, one is steadfast in truth. Whoever worships me as life and immortality attains all life here and immortality hereafter.” Some say the breaths go separately, but truly, all are united—speech, sight, hearing, mind, and breath each reveal the whole through their own faculty. Thus, Indra declared, is the attainment of the highest by the breaths. It is observed that speech, sight, hearing, and even the mind may depart from a living person—yet life continues. One may be mute, blind, deaf, or even childish in mind, yet live. Even if a limb is lost, life persists. But Breath alone, the self of wisdom, sustains the body. Therefore, one should worship this Breath, for Breath and wisdom dwell in the body together and depart together. When a person sleeps and sees no dreams, Breath alone remains unified within. Speech, sight, hearing, and mind all merge into it. Upon awakening, as sparks fly from a blazing fire, the breaths disperse to their places, reaching from the self to the gods and from the gods to the worlds. This is true both in sleep and as one approaches death: when the mind and senses withdraw, Breath alone remains unified, and upon awakening or departing, the breaths return to their domains. When one finally departs from the body, he takes with him all these faculties: with speech, all names; with breath, all scents; with sight, all forms; with hearing, all sounds; with mind, all thoughts. In Breath is the attainment of all. Breath is wisdom, and wisdom is breath; they dwell and depart together. All the faculties—speech, nose, eye, ear, tongue, hands, body, sexual organ, feet, and wisdom itself—are limbs of wisdom, each with their corresponding elemental principle established beyond. By wisdom, one ascends each faculty and, through each, attains its domain: all names, scents, forms, sounds, essences of food, actions, pleasures and pains, bliss and offspring, movement, and intelligence. Without wisdom, none of these faculties can reveal their objects—speech cannot speak, sight cannot see, hearing cannot hear, and so on, unless the mind, the seat of wisdom, is present. Without wisdom, there is no true accomplishment or discernment. Thus, one should not seek to know the objects—the spoken, the seen, the heard—but rather the knower: the speaker, the seer, the hearer, the thinker. The ten elemental principles are governed by wisdom, and wisdom by the elements; neither exists without the other. No form arises from either alone; they are not separate. Just as the rim of a wheel is fixed on the spokes and the hub on the rim, the elemental principles are fixed on the wisdom principles, and both are fixed on Breath. This Breath is the self of wisdom: blissful, ageless, immortal. By good deeds, one does not become greater; by evil, not lesser. This self is the cause of all actions and the ruler of all. Let one know: “This is my self.” Now comes the story of Gārgya, son of Bālākira, a student who traveled among many peoples and finally came to Ajātaśatru, king of Kāśi, offering to teach him about Brahman. Ajātaśatru welcomed him with a gift. In the ensuing dialogue, Gārgya described various cosmic persons—those in the sun, moon, lightning, thunder, sky, wind, fire, waters, mirror, echo, sound, shadow, body, dream, and the eyes—each time offering his worship. But Ajātaśatru corrected him, explaining the true nature of each and how one who meditates on them attains only their limited qualities, not the ultimate. When Bālākī fell silent, Ajātaśatru asked if that was all he knew. When Bālākī admitted it was, Ajātaśatru said, “In vain have you meditated. I will tell you about Brahman.” He explained: “Whoever is the maker of all these persons, whose work this is, he is to be known.” Bālākī, humbled, sought instruction. Ajātaśatru took him to a sleeping man. Calling to him yielded no response; striking him, the man awoke. Ajātaśatru asked where the person within had gone and from where he returned. Bālākī did not know. Ajātaśatru explained: Within the heart are many fine arteries, colored and subtle, in which the self dwells. When one is in dreamless sleep, he becomes one with the vital breath alone; all faculties merge into him. Upon awakening, the breaths scatter to their places, as sparks from a fire. Just as a razor is placed in its case or a spider in its web, so the intelligent self resides in the body. This self, once realized, is at peace, enjoying with all these faculties as a master with his people. As long as Indra did not know this self, the Asuras overpowered him. When he knew, he conquered all and became supreme. Likewise, one who knows this self destroys all evils and attains sovereignty over all beings. Such is the wisdom of the Kauṣītaki Upaniṣad: the supreme unity of Breath and wisdom, the true self within, and the path to immortality and lordship for one who knows.
