[Vâg. S. XXXVII, 12,] 'Unmolested thou art in front (in the east),'--for unmolested by the Rakshas, the fiends, indeed, this (earth) is in front;--'in Agni's over-lordship,'--he thus makes Agni her over-lord for the warding off of the fiends, the Rakshas;--'grant thou life unto me!'--he thus secures life for himself, and accordingly he attains the full (term of) life.
