Aitareya Upanishad • I.3.6

He brought a horse to them the deities/senses. They said, "Indeed, this is not enough for us." 2

He brought a man Purusha The human form, seen here as the crown of creation to them. They said, "Well done, indeed!" original: "sukrtam bata". This is a play on words: man is "well-made" and also the "performer of good deeds." Truly, man is well-made. He said to them, "Enter into your respective abodes." 3

Fire, becoming speech, entered the mouth. Air, becoming breath, entered the nostrils. The Sun, becoming sight, entered the eyes. The Directions, becoming hearing, entered the ears. Herbs and trees, becoming hairs, entered the skin. The Moon, becoming the mind, entered the heart. Death, becoming the out-breath apana, entered the navel. The Waters, becoming semen, entered the generative organ. 4

Hunger and Thirst said to Him the Creator, "Assign a place for us." He said to them, "I assign you a place within these very deities; I make you sharers with them." Therefore, to whatever deity an offering is made, Hunger and Thirst become sharers in it. This explains why human physiological needs like hunger are inextricably linked to our sensory and vital functions. 5

He thought, "Here now are the worlds and the guardians of the worlds. Let me create food for them." 1

He brooded over the waters used the heat of consciousness/austerity. From the waters thus brooded over, a form was born. That form which was born is indeed food. 2

Having been created, this food tried to run away. He the first embodied being tried to seize it with speech. He was not able to seize it with speech. If he had seized it with speech, then by merely uttering the name of food, one would have been satisfied. 3
