Let us contemplate the profound teachings of the Brhadaranyaka Upanishad, where the mysteries of attainment, abode, procreation, and the vital forces are revealed. The scripture declares that whoever truly understands the nature of attainment, to him, attainment comes. Whatever he desires, he receives. The ear itself is the means of attainment, for within the ear, all the Vedas are realized. Thus, for one who knows this truth, all his desires are fulfilled. In the same way, whoever knows what is the true abode becomes the abode for his people and for humankind. The mind is the abode; by understanding this, one becomes the refuge and support of his own and of others. Likewise, the secret of procreation is revealed: whoever knows its essence is born with offspring and cattle. Semen is indeed procreation; thus, one who knows this is blessed with progeny and abundance. Now, the vital forces within the body once disputed among themselves, each seeking to know which was the most excellent. They approached Brahman, the Supreme, and asked, “Who among us is the greatest?” Brahman answered, “The one whose departure makes this body seem inferior, he is the most excellent.” To test this, speech departed first. After staying away for a year, she returned and asked the others, “How did you live without me?” They replied, “Just as mute people live—by breath, by seeing with the eye, by hearing with the ear, by knowing with the mind, and by procreating with semen—so we lived.” Speech returned to its place. Next, the eye left for a year. Upon returning, it asked, “How did you live without me?” They answered, “Just as the blind live—without seeing, but breathing, speaking, hearing, thinking, and procreating—so we lived.” The eye entered again. Then, the ear departed. After a year, it returned and asked, “How did you live without me?” The others said, “Just as the deaf live—without hearing, but breathing, speaking, seeing, thinking, and procreating—so we lived.” The ear rejoined them. The mind, too, departed for a year. Upon return, it asked, “How did you live without me?” They replied, “Just as the dull-witted live—without thinking, but breathing, speaking, seeing, hearing, and procreating—so we lived.” The mind entered again. Finally, semen departed. After a year, it returned and asked, “How did you live without me?” The others said, “Just as the impotent live—without procreation, but breathing, speaking, seeing, hearing, and thinking—so we lived.” Semen returned. Then, breath prepared to depart. All the other forces gathered themselves together, like a noble Sindhu horse collecting its limbs, and pleaded, “Do not leave us, revered one; we cannot live without you.” Breath replied, “Then offer me your tribute.” They agreed. Each force offered its tribute: speech said, “Because I am the best, you are also the best.” The eye said, “Because I am the foundation, you are also the foundation.” The ear said, “Because I am prosperity, you are also prosperity.” The mind said, “Because I am the abode, you are also the abode.” Semen said, “Because I am progeny, you are also progeny.” Breath asked, “What is my food and clothing?” They answered, “Whatever is among horses, animals, insects, and flying creatures—that is your food; water is your clothing.” Indeed, nothing eaten is without food, nothing received is without food; for one who knows this, whatever he eats is never without food. Those who know this, the wise, eat and sip water, and after eating, sip water again, believing that by doing so, they purify their food. Thus, one who knows should sip water before and after eating, to make his food pure. If someone wishes to attain greatness, he should, during the bright fortnight of the lunar month, on auspicious days, after observing the twelve-day upasad vow, gather fruits from the udumbara tree and all medicinal plants, anoint them, establish the fire, cover with ghee, prepare and churn them under the constellation of Pūṣā, then offer oblations. He prays: “As many gods as are in you, O Jātavedas, who obstruct the desires of man, to them I offer their share; may they, satisfied, fulfill my desires. Svāhā.” He worships: “When you lie down as a quadruped, I am the supporter; with the stream of ghee I worship you, O provider. Svāhā. May offspring arise, and may these not go elsewhere.” Thus, he offers the third oblation. He continues, offering oblations for the eldest, the best, for breath, for speech, for the eye, for the ear, for the mind, for semen, for being, for becoming, for the universe, for all, for earth, for atmosphere, for heaven, for the directions, for Brahman, for Kṣatra, for Bhūḥ, for Bhuvaḥ, for Svaḥ, for Bhūrbhuvaḥ, for Agni, for Soma, for brilliance, for splendor, for prosperity, for Savitṛ, for Sarasvatī, for all the gods, and for Prajāpati—each time pouring the essence from the churn into the fire with the sacred word, “Svāhā.” He touches the offering, declaring: “You are movement, you are blazing, you are fullness, you are firmness, you are unity, you are affirmation, you are being affirmed, you are the chant, you are being chanted, you are heard, you are being heard, you are moist and kindled, you are abundant, you are mighty, you are light, you are food, you are death, you are absorption.” He lifts it, saying: “You are raw. May you, with me, be a sovereign ruler; may the sovereign ruler make you a sovereign ruler.” He sips water, reciting: “That Savitṛ, the most excellent, honeyed winds blow for the truth, honeyed rivers flow; may the herbs be honeyed for us.” Bhūḥ, svāhā. He continues: “May we meditate upon the radiance of the divine; honeyed are the nights and dawns, honeyed is the earthly dust, honeyed is heaven, our father.” Bhuvaḥ, svāhā. “May the intellect inspire us. May the honeyed forest be ours, may the sun be honeyed, may the cows be honeyed for us.” Svaḥ, svāhā. He recites the entire Sāvitrī, all the honeyed verses, all the utterances: “May I become all this.” Bhūrbhuvaḥ Svaḥ, svāhā. After sipping water, washing his hands, he sits with his back to the fire. In the morning, he approaches the sun, saying: “You are the single lotus among the directions; may I become the single lotus among men.” Having approached thus, sitting by the fire with his back, he recites the verse. Thus did Uddālaka Āruṇi, disciple of Yājñavalkya of the Vājasaneyas, declare: “If one were to sprinkle dry stumps, branches would grow, leaves would sprout.” Yājñavalkya of the Vajasaneyins spoke this to his student Madhuka, son of Paingi: “If one were to sprinkle dry wood with this, branches would grow, leaves would sprout.” Madhuka, son of Paingi, spoke this to his student Chuda, son of Bhagavitta: “If one were to sprinkle dry wood with this, branches would grow, leaves would sprout.” Chuda, son of Bhagavitta, spoke this to his student Janaka, son of Ayasthuna: “If one were to sprinkle dry wood with this, branches would grow, leaves would sprout.” Janaka, son of Ayasthuna, spoke this to Satyakama, son of Jabala: “If one were to sprinkle dry wood with this, branches would grow, leaves would sprout.” Satyakama, son of Jabala, spoke this to his students: “If one were to sprinkle dry wood with this, branches would grow, leaves would sprout.” This sacred knowledge should not be taught to one who is not a son or not a student. There are four things made from udumbara wood: the udumbara ladle, the udumbara sacrificial spoon, the udumbara fuel, and the two pieces for kindling. There are ten kinds of cultivated grains: rice, barley, sesame, beans, anupriyangu, wheat, lentils, khalva, and khalakula. Half of each is ground, moistened with curds, honey, and ghee, and clarified butter is offered. Of all beings, the essence of the earth is plants; of plants, flowers; of flowers, fruit; of fruit, man; of man, semen. Prajapati, the Lord of Creatures, considered, “Let me establish a foundation here.” He created her through desire and worshipped her, thus establishing prosperity. Therefore, one should worship a woman, for she is prosperity. He raised the stone facing east and with it created her. Her altar is her lap; her hair is the sacred grass; her skin is the two covering stones; and the fire is kindled in the middle, which is the vulva. Whoever, knowing this, has intercourse with a woman in the manner of the Vajapeya sacrifice, attains a world as great as that. But if one who does not know this has intercourse, the woman takes his merit. Uddalaka Aruni, Nakha Maudgalya, and Kumara Harita, knowing this, declared: “Many noble Brahmins, lacking self-control and merit, depart from this world, who, not knowing this, have intercourse.” Indeed, for many, semen is emitted either while asleep or awake. He should touch it and recite: “Whatever semen of mine has fallen to the earth today, whatever has entered plants or water, this semen I take back. May my strength return to me, may my vigor, may my fortune return; may the household fires be established in their places.” Taking it with the ring finger and thumb, he should touch between the breasts or the eyebrows. If he sees water as his own self, he should recite: “May energy, strength, fame, wealth, and merit be in me.” Indeed, the menstrual cloth is the prosperity of women. Therefore, approaching a woman wearing a menstrual cloth, one should address her with reverence. If she gives it to him, and he desires her, he should satisfy her desire; if she gives it to him herself, and he desires her, he should touch her with a staff or with his hand and then unite with her; “With your strength and fame I take your fame,” thus he becomes inglorious. Such are the sacred instructions of the Upanishad, revealing the subtle truths of attainment, the vital forces, ritual, essence, and prosperity, guiding the seeker to wisdom and fulfillment.
