YV 1.5n

For him who desires prosperity should be used (the fire) which comes to life from the pan, for from it is it produced, it is self-produced by name; verily he becomes prosperous. If he desire of a man, 'May I produce a foe for him', he should take for him (fire) from elsewhere, and deposit it; verily straightway he produces a foe for him. From a frying-pan he should (take fire) and deposit (it) for one who desires food; in a frying-pan food is kept; verily he wins food with its birth place [4]. He deposits Muñja grass; Muñja is strength; verily he bestows upon him strength. Agni departed from the gods, he entered the Krumuka wood; he deposits Krumuka; verily he wins what of Agni is there imbued. With butter he joins (it); butter is the dear home of Agni; verily he unites him with his dear abode, and with brilliance also [5]. He puts on (a stick) of Vikankata wood; verily he wins radiance; he puts on one of Çami, for atonement. 'Do thou sit down in the lap of this mother', with three (verses) he adores (the fire) when born; three are these worlds; verily he attains reputation in these worlds; verily also he bestows breaths on himself. Formerly Agni would not burn what was not cut by the axe, but Prayoga, the seer, made that acceptable to him. 'Whatever logs we place on thee', (with these words) he puts on a kindling-stick; verily he makes what is not cut by the axe acceptable to him; all is acceptable to him who knows thus. He puts on one of Udumbara wood; the Udumbara is strength; verily he confers strength upon him. Prajapati created Agni; him on creation the Raksases [1] were fain to destroy; he saw that (hymn) of the Raksasslaying (one); therewith he smote away the Raksases; in that it is (the hymn) of the Raksas-slaying one, thereby he drives away the Raksases from Agni when born. He puts on one of Açvattha wood; of trees the Açvattha is the overcomer of foes; (verily it serves) for victory. He puts on one of Vikankata; verily he wins light.
