2.5.18

Verily Dadhyak Atharvana proclaimed this honey to the two Asvins, and a Rishi, seeing this, said: `He (the Lord) made bodies with two feet, he made bodies with four feet. Having first become a bird, he entered the bodies as purusha (as the person).' This very purusha is in all bodies the purisaya, i.e. he who lies in the body (and is therefore called purusha). There is nothing that is not covered by him, nothing that is not filled by him.
