They said, 'Meditate ye!' whereby, doubtless, they meant to say, 'Seek ye a layer!' Whilst meditating they saw this second libation, and offered it: after offering it, they saw the Visvagyotis (all-light bricks), that is, those deities Agni, Vâyu, and Âditya; for these deities are indeed all the light. And in like manner does the Sacrificer now, after offering those two libations, see the fire-pan, these worlds; and those all-light deities. He offers with two interlinked (verses): he thereby interlinks these worlds, and those deities.
