YV 1.5h

He gathers with the ass; therefore the ass, even when grazing is bad, becomes fat beyond other animals, for by it they gather food and light. He gathers with the ass; therefore the ass, being of double seed, is born as the least of animals, for Agni burns his place of birth. Now he is mounted upon offspring [5], and is strong to burn with pain offspring. 'Be auspicious, for offspring', he says; verily he makes him calm for offspring. '(For offspring) of man, O Angiras', he says, for offspring are of men. 'Scorch not sky and earth, nor the atmosphere, nor the trees', he says; verily he makes him calm for these worlds. 'Let the steed advance, thundering', he says, for he is a steed. 'The sounding, the donkey, the flier' [6], he says, for the seers called him the 'donkey'. 'Bearing Agni of the dust', he says, for he bears Agni. 'May he fall not before his day', he says; verily he bestows life upon him; therefore an ass lives all its days; therefore are men afraid when an ass perishes before its day. 'The strong, bearing the strong Agni', he says, for he is strong, and Agni is strong. 'Germ of the waters [7], him of the ocean', he says, for Agni is the germ of the waters. 'O Agni, come hither for enjoyment', (at these words) the two worlds burst apart; in that he says, 'O Agni, come hither for enjoyment', it is for the separation (vityai) of these worlds. He, having left his place and not having reached a support, then thinks of the Adhvaryu and the sacrificer; 'holy order and truth', he says; holy order is this (earth), truth [8] is yonder (sky); verily in these two he establishes him, and neither the Adhvaryu nor the sacrificer is ruined. Agni when tied up, as Varuna, attacks the sacrificer; 'O plants, do ye accept Agni here', he says, for atonement. 'Casting aside all hostilities, all evil imaginings', he says, to smite away the Raksases. 'Sitting down, may he smite away from us misfortune', he says, for support.
