1. ‘I choose the roaring, animal-like form of the Sāman’—such is the Udgītha belonging to Agni. The indistinct form belongs to Prajāpati; the distinct, to Soma; the soft and smooth, to Vāyu; the smooth and strong, to Indra; the

heron-like, to Bṛihaspati; the ill-sounding, to Varuṇa. One may practise all these, but one should avoid that belonging to Varuṇa.
