In plain words
Now this was unuttered. That real one, Prajāpati, having performed austerity, uttered forth bhūḥ, bhuvaḥ, svaḥ. This is the coarsest body of that Prajāpati, the one that has the worlds: svaḥ is its head, bhuvaḥ its navel, bhūḥ its feet, and the sun its eye. For the eye is the great measure that is stretched out for a person, since it is by the eye that he moves among measures. The eye indeed is the real; for the person set in the eye moves among all objects. Therefore let a man worship with bhūḥ, bhuvaḥ, svaḥ; for by this Prajāpati is worshipped as the self of all, as the eye of all. So it is said: "This is the world-bearing body of Prajāpati; in it all this is hidden, and it is hidden in all this. Therefore let a man worship this."
