Taittiriyaka-Upanishad: First Valli, Seventh Anuvaka
1. “The earth, the sky, heaven, the four quarters,and the intermediate quarters,”—“Agni (fire), Vayu (air), Aditya (sun), Kandramas (moon), and the stars,”—“Water, herbs, trees, ether, the universal Self (virag),”—so much with reference to material objects (bhuta).
Now with reference to the self (the body): “Prâna (up-breathing),Apana (down-breathing),Vyana (backbreathing), Udana (out-breathing), and Samana (on-breathing),”—“The eye, the ear, mind, speech, and touch,”—“The skin, flesh, muscle, bone, and marrow.” Having dwelt on this (fivefold arrangement of the worlds, the gods, beings, breathings, senses, and elements of the body), a Rishi said: “Whatever exists is fivefold (pankta).”
(1) By means of the one fivefold set (that referring to the body) he completes the other fivefold set.
