YV 4.2h

'Let free the rain from heaven; with waters fill the ocean', he says; verily these and yonder waters he unites; then with these he approaches yonder (waters). 'Thou art born of waters, first-born; thou art the might of the ocean', he says; that is according to the text. 'Flood the earth', (with these words) he offers in a Boerhavia procumbens; this of plants is that which wins rain, and thereby he causes rain to fall. 'The gods whose portion is in the sky', (with these words) he shakes the black antelope skin; verily to him these worlds become dear and desired. 'All' the metres are to be recited in this sacrifice', they say; the Kakubh is the strength of the Tristubh, the Usnih of the Jagati; in that he repeats the Usnih and the Kakubh, thereby he wins all the metres. The Usnih is the Gayatri; the four syllables over are fourfooted cattle; just as cake is over cake, so it is with the syllables which are over the verse; if he were to close with a Jagati [1], he would end the sacrifice; he closes with a Tristubh, the Tristubh is power and strength; verily he establishes the sacrifice on power and strength, he does not end it. 'O Agni, three are thy strengths, three thy abodes', with this (verse) containing the word 'three' he closes, for similarity of form: that which has three constituents is the whole of the sacrifice; for every desire it is employed, for the sacrifice is employed for all desires. He who is practising witchcraft should sacrifice with that of three constituents; that which has three constituents is the whole of the sacrifice [2]; verily with the whole of the sacrifice he bewitches him, and lays him low. With the same (offering) should he sacrifice who is practised against, that which has three constituents is the whole of the sacrifice; verily he sacrifices with the whole of the sacrifice, and he who practises witchcraft does not lay him low.
