By means of the sacrifice the gods went to the world of heaven; they reflected, 'Men will follow after us here'; they blocked (the way) by the year and went to the world of heaven. It the Rsis discerned by means of the season−cups; in that the season−cups are drawn, (they serve) to reveal, the world of heaven. Twelve are drawn; the year consists of twelve months; (verily they serve) to reveal the year. The first two are drawn together, the last two together; therefore the seasons are in pairs. The season−vessel has mouths on both sides, for who [1] knows where is the mouth of the seasons? 'Give directions for the season', six times he says,' the seasons are six; verily he delights the seasons; 'For the seasons', four times; verily he delights four−footed cattle; twice again he says, 'For the season'; verily he delights two−footed (cattle). 'Give directions for the season', six times he says; 'For the seasons', four times; therefore four−footed cattle depend upon the seasons; twice [2] again, 'For the season', he says; therefore bipeds live upon quadrupeds. 'Give directions for the season', six times he says; 'For the seasons', four times; twice again, 'For the season'; verily the sacrificer makes himself a ladder and bridge to attain the world of heaven. One should not follow the other; if one were to follow the other, season would follow season, the seasons would be confused [3]; therefore in order the Adhvaryu sets out by the southern (door), the Pratiprasthatr by the northern; therefore the sun goes south for six months, north for six months.' 'Thou art taken with a support; thou art Samsarpa; to Anhaspatya thee!' he says; 'There is a thirteenth month', they say; verily he delights it.
