Let us enter the sacred discourse of the Praśna Upaniṣad, where seekers gathered to question the mysteries of existence. The sages spoke first of the father, Prajāpati, the cosmic progenitor. They described him as having five feet and twelve forms, dwelling in the upper city of the body. The wise further revealed that he is set within a chariot with seven wheels and six spokes, symbolizing the intricate cycles of creation. They explained that the month itself is Prajāpati. Its dark fortnight represents matter, while the bright fortnight embodies the life-breath. Thus, seers perform sacrifices during the bright half, seeking the vitality that comes from life-breath, not from inert matter. Day and night, too, are Prajāpati. Day is the life-breath; night is matter. If people unite in sexual intercourse by day, it is said to waste the life-breath, but union by night is considered celibacy, preserving spiritual energy. Food is Prajāpati, and from food arises semen. From semen, all beings are born, showing the sacred continuity of life. Those who uphold the vow of Prajāpati—practicing austerity, celibacy, and truth—are blessed with offspring and attain the world of Brahman. For these pure souls, untouched by crookedness, falsehood, or deceit, there exists a stainless realm of Brahman. Thus ended the first inquiry. Then Bhārgava, son of Vaidarbhi, approached with reverence and asked, “Venerable sir, how many gods uphold the creation? Which illumine it? Who among them is the greatest?” The teacher replied, “Space, air, fire, water, earth, speech, mind, eye, and ear—these gods manifest their powers and declare, ‘We hold this body together, supporting it by our strength.’” But Prāṇa, the foremost among them, spoke, “Do not be deluded. It is I alone, dividing myself fivefold, who uphold and support this body.” Yet the others did not believe him. Out of pride, Prāṇa seemed to rise upward. As he rose, the others rose with him. When he remained, they remained. Just as bees follow their king, so speech, mind, sight, and hearing, pleased, praised Prāṇa. They declared, “He is Agni who burns, the Sun who shines, Parjanya who brings rain, Vāyu the wind, Earth the Lord of wealth, the true and untrue, and the immortal. Just as spokes are fixed in the hub of a wheel, so everything—Vedas, sacrifice, kingship, priesthood—is established in Prāṇa.” They continued, “You, Prāṇa, move as Prajāpati in the womb and are reborn again and again. Creatures offer to you, for you are established in the prāṇas. Among gods, you are radiant; among ancestors, the first offering; among seers, the truth of conduct; you are Atharvan and Aṅgiras. You are Indra by brilliance, Rudra the protector, you move in the mid-region, and you are the Sun, lord of lights. When you shower down, creatures rejoice, hoping for food as they desire. You are the wanderer, the single charioteer, the lord of all. We offer you the first portion; you are our father, O Mātariśvan.” They prayed, “May the form of yours established in speech, hearing, sight, and mind be auspicious for us; do not depart. All that exists in the three worlds is under your control, Prāṇa. Protect us as a mother protects her children; grant us prosperity and wisdom.” Thus ended the second question. Then Kauśalya, son of Aśvalāyana, asked, “Venerable Sir, from where is Prāṇa born? How does it enter the body, divide itself, and depart? How does it support what is outside and within?” The teacher replied, “You ask beyond the ordinary, and are devoted to Brahman, so I will tell you. From the Self, Prāṇa is born. As a shadow is cast by a person, so Prāṇa is spread in the Self. By the mind’s action, it enters the body.” He continued, “Just as a king appoints officers to rule over villages, Prāṇa assigns functions to the other prāṇas. Apāna governs excretion and generation; Prāṇa itself resides in the eyes, ears, mouth, and nostrils; Samāna dwells in the middle, distributing food equally. Thus, there are seven flames. The Self is in the heart, from which a hundred and one nāḍīs branch out. Each has a hundred branches, and each branch seventy-two thousand sub-branches, where Vyāna moves. Udāna rises upward; by virtue, it leads to the virtuous world; by vice, to the sinful world; by both, to the human world.” “The sun is the external Prāṇa, supporting the Prāṇa of the eyes. The earth supports Apāna. The space between is Samāna; air is Vyāna. The upward-moving energy is radiance; when radiance is calmed, the senses merge into the mind and return to rebirth. With whatever mind one departs, with that he goes to the life-breath, which, endowed with radiance and accompanied by the self, leads him to the world shaped by his intention.” “Whoever knows the life-breath as described—his offspring do not perish; he becomes immortal. He who knows the origin, entry, place, pervasiveness, and fivefold nature of the life-breath attains immortality.” Thus ended the third question. Then Sauryāyaṇi Gārgya asked, “Venerable sir, in this person, what sleeps, what remains awake, who sees dreams, whose happiness is this, and in whom do all these rest?” The teacher replied, “Gārgya, just as the sun’s rays merge in its circle of light at sunset and spread out at sunrise, so all faculties merge in the supreme deity, the mind. At that time, the person neither hears, sees, smells, tastes, touches, speaks, grasps, enjoys, releases, nor moves; they say, ‘he sleeps.’” “Only the foremost life-breath remains awake in the city of the body. The downward-moving breath is like the household fire; the diffusive breath is like the fire for cooking; and from the household fire, the sacrificial fire is kindled, which is the upward-moving breath. The equalizing breath brings together the two offerings—exhalation and inhalation. The mind is the sacrificer; the upward-moving breath is the fruit of the sacrifice, leading the sacrificer day by day to Brahman.” “In dreams, this deity experiences his greatness: what has been seen, heard, and experienced in various places and directions, he experiences again and again. He sees the seen and unseen, heard and unheard, experienced and unexperienced, real and unreal—he sees all.” “When overpowered by radiance, this deity does not see dreams; then, in the body, he experiences happiness. Just as birds gather on a tree, so all these faculties rest in the supreme self.” “Earth and its essence, water and its essence, fire and its essence, air and its essence, space and its essence; the eye and what is seen, the ear and what is heard, the nose and what is smelled, taste and what is tasted, skin and what is touched, speech and what is spoken, hands and what is grasped, the generative organ and what is enjoyed, the anus and what is excreted, feet and what is moved, mind and what is thought, intellect and what is understood, ego and what is asserted, consciousness and what is contemplated, radiance and what is illuminated, life-breath and what is sustained—all these rest in the supreme self.” “He is the seer, toucher, hearer, smeller, taster, thinker, knower, doer—the self of knowledge, the person. He rests in the supreme, imperishable self.” “Whoever knows that which is without shadow, without body, colorless, pure, and imperishable attains the highest imperishable. He becomes all-knowing and all.” Thus, the sacred questions were answered, illuminating the profound unity of life, breath, and Self.
