[Vâg. S. XI, 54] 'The Rudras, having mixed the earth, kindled the great light;'--for this Agni is yonder sun: thus it is that great light which the Rudras, having mixed the earth, did kindle;--'yea, never-failing and brilliant, their light shineth among the gods;'--for that never-failing and brilliant light of theirs does indeed shine among the gods.
