[Vâg. S. XII, 13; Rik S. X, 1, 1] 'The great hath stood up erect before the Dawns,'--for before the dawn the great one (Agni) indeed stands up erect;--'emerged from the gloom he hath come with light,'--for emerged from the gloom, the night, he indeed comes with light, with the day;--'well-shapen with white light,'--for he, Agni, is indeed well-shapen with white light;'--'when born, he hath filled all homesteads;'--all homesteads, doubtless, means these worlds, and these he indeed fills, when born. He holds him up so as to be beyond the reach of the arms, for he (the sun) is beyond the reach of arms from here. He then lowers him: he thereby comes back to this resting-place, and stands firmly on this resting-place. [He does so] with a gagatî verse, for the Gagatî gains these worlds from above hitherwards.
