YV 1.5g

In that he digs he acts as it were harshly to this (earth); he pours water down, the waters are appeased; verily with the waters appeased he calms her pain. 'May for thee Vayu, Matariçvan unite', he says; Vayu is breath; verily with breath he unites her breath; 'may for thee Vayu', he says; therefore the rain speeds from the sky, made to fall by Vayu. 'To him, O goddess, be Vasat with thee' [1], he says; the seasons are six; verily upon the seasons he bestows rain; therefore in all the seasons it rains. If he were to utter the Vasat cry, his Vasat cry would be exhausted; if he were not to utter the Vasat cry, the Raksases would destroy the sacrifice; 'Vat', he says; verily, mysteriously he utters the Vasat cry; his Vasat cry is not exhausted, the Raksases do not destroy the sacrifice. 'Well born with light', (with these words) he ties up with an Anustubh verse; all the metres are the Anustubh [2], Agni's dear body is the metres; verily he encircles him with his dear body; likely to win a garment is he who knows thus. Agni when tied up is connected with Varuna; 'Arise, thou of fair sacrifice', 'Arise, erect, to aid us', with two (verses) addressed to Savitr he rises up; verily, instigated by Savitr, he sends aloft the wrath of Varuna that is in him; with two (verses) (he arises), for support. 'Born, thou art the child [3] of the two worlds, he says; the two worlds are these two (sky and earth), Agni is the child of the two; therefore he says thus. 'O Agni, brilliant, distributed among the plants', he says, for when they distribute him, then he becomes more brilliant. 'Thou didst come thundering from thy mothers', he says; his mothers are the plants; verily from them he makes him to fall. 'Be firm, of strong limbs', (with these words) he places (Agni) on the ass [4]; verily thereby he yokes it for strength. He gathers with the ass; therefore the ass is the best burden- gatherer of animals.
