अथ यदवोच भुवः प्रपद्य इत्यग्नि प्रपद्येवायु प्रपद्य आदित्य प्रपद्य इत्येव तदवोचम् ॥ ६ ॥
In plain words
Now, when I spoke the words 'I take refuge in the world of the mid-space,' what I meant was precisely this: 'I take refuge in Agni, I take refuge in Vāyu, I take refuge in Āditya.'
Close to the Sanskrit
Now, what I spoke as 'I resort to bhuvaḥ',—[by that] 'I resort to Agni, I resort to Vāyu, I resort to Āditya', precisely that I spoke.
