atha vaiśvadevīm purorucam śaṃsati / (soma: prātaḥ savana)

xiv. 5. Then he recites a Puroruc addressed to the All-gods. It is of six feet; the seasons some call it. The seasons are six; he recites each two feet of it separately; therefore the seasons are united in pairs and called 'Summer, the rains, and winter.' Some recite the Puroruc for Sarasvatī; he should not do so; it is superfluous; speech has of itself radiance; speech is the Puroruc. 'O Vāyu, come hither, O lovely one' and 'O Açvins, sacrificial food', these two (hymns) are the Praüga; (they are) of nine verses and of twelve verses; these make twenty-one; the four (verse) Stoma, the highest of Stomas, is twenty-onefold; thus he obtains the highest Stoma; in that, further, there are twenty-one, and the months are twelve, the seasons five, these worlds three, and yonder sun the twenty-first, verily thereby he places the sacrificer in identity of world with (the sun). There are seven triplets; the metres are seven; verily (they serve) to obtain all the metres. Moreover with these the gods appropriated the seven heptads of the Asuras; verily thus also the sacrificer appropriates the seven heptads of the rival who hates him. In the beginning the morning pressing was Agni's, the midday pressing Indra's, the third pressing the All-gods'. Agni desired 'Let me have a share in the midday pressing, also in the third pressing.'
