vii. 9. He falls away as it were from this world who advances with the introductory sacrifice; in that he inverts (the verses), thus he finds support in this world on a support which cannot be moved. Moreover the metres are the breaths; verily thus in the self he intertwines the breaths, to prevent severance; therefore these breaths though blowing in diverse directions do not blow out. ‘Thee, O thou of most varied fame,’ ‘What is best, that to Agni,’ are the Anuṣṭubh invitatory and offering verses (of the Sviṣṭakṛt offering). The introductory sacrifice is the continuance of the sacrifice, the concluding sacrifice is speech; the Anuṣṭubh is speech; with speech the sacrifice is continued. These two he does not invert, (thinking) ‘The invitatory and offering verses are supports; let me not intertwine two supports.’ (The sacrifice) ends with the Çamyuvāka; that is the symbol of approach. It is as if having advanced one should dwell in the vicinity of the world of heaven. Again, as to (the sacrifice) ending with the Çamyuvāka, all the deities unite in the introductory sacrifice; he who would here cause joint offering to be made to the wives with (the gods), it would be as if he were to bring the wives of the gods to the place of their assembling; then it would be as if a man there were to say of him, ‘This (fellow) has brought the wives of the gods to the place of their assembly; his wife will be following him to the assembly’. Therefore it ends with the Çamyuvāka, to prevent the coming together of the deities.
