YV 1.2i

He whose ancestors and himself for three generations have not drunk Soma should offer (a bull) which has again been let loose to Indra and Agni; the Soma drinking of a Brahman is interrupted if his ancestors and himself for three generations have not drunk Soma [5]; verily he has recourse to Indra and Agni with their own share; verily they bestow on him the drinking of Soma, the drinking of Soma comes to him. In that it is offered to Indra, the Soma drink is power; verily he wins power, the Soma-drink. In that it is offered to Agni, the Brahman is connected with Agni, verily he continues his own deity. It is let loose again, for his drinking of Soma is as it were let loose again [6]; (verily it serves) for prosperity. When practising witchcraft, he should offer a hornless (beast) to Brahmanaspati; verily he has recourse to Brahmanaspati with his own share; verily he cuts him down to him; swiftly he reaches destruction. It is a hornless one; prosperity is razor-edged; in that it is hornless, (it serves) for prosperity. The sacrificial post is shaped like a wooden sword; the wooden sword is a thunderbolt; verily he hurls a thunderbolt against him; the strew is made of Çara grass; verily he crushes him; the kindling-wood is of Vibhidaka; verily he splits him. He who desiring a village desires, 'May I be the back of my equals', should offer to Brhaspati (a beast) with a white back; verily he has recourse to Brhaspati with his own share; verily he makes him to be the back of his peers; he becomes possessed of a village. It is with a white back, for it has Brhaspati as its deity; (verily it serves) for prosperity. He who desires food should offer a dark (beast) to Pusan; Pusan is food; verily he has recourse to Pusan with his own share; verily he gives him [1] food; he becomes an eater of food. It is dark, that is the form of food; (verily it serves) for prosperity.
