'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): 'Prana (up-breathing), Apana (down-breathing), Vyana (back-breathing), 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).' By means of the one fivefold set (that referring to the body) he completes the other fivefold set.
In plain words: The text lists things in the world in groups of five, like earth, sky, heaven and the directions, or fire, air, sun, moon and stars. It also lists the body in groups of five, like five kinds of breath, five senses, and skin, flesh, muscle, bone and marrow. A sage concluded that everything comes in fives, and that the fives inside the body match and complete the fives outside it.
