[Vâg. S. XI, 65] 'May the Vasus fill thee with the Gâyatrî metre, Aṅgiras-like!--May the Rudras fill thee with the Trishtubh metre, Aṅgiras-like!--May the Âdityas fill thee with the Gagatî metre, Aṅgiras-like!--May the All-gods, dear to all men, fill thee with the Anushtubh metre, Aṅgiras-like!'--by these deities he thus moistens it: by whatever deities he fashions it, by them he fumigates it, and by them he moistens it. For he who performs a work, knows the practice of it: hence by whatever deities he fashions it, by them he fumigates and moistens it.
