YV 4.7d

Now the Trivrt is brilliance; verily they place brilliance in themselves. There is a praise of Indra with the Pañcadaça; verily they win power (indriyá) [3]. There is a Saptadaça, for the winning of food; verily by it they are propagated. There is an Ekavinça, for support; verily they place radiance in themselves. There is a Caturvinça. Twenty-four half-months make up the year, the year is the world of heaven; verily they find support in the year, the world of heaven. Now there is the chief (day), and those who knowing thus perform (the rite of) these (nights) become the chief. From the Caturvinça they go to the Prsthas. Verily having found support in the year [4] they attain the gods. From the Trayastrinça they go to the Trayastrinça. The gods are three and thirty; verily in the gods they find support. There is a Trinava. The Trinava is these worlds; verily in these worlds they find support. There are two Ekavinças, for support; verily they place radiance in themselves. There are many Sodaçins, and therefore there are many males among offspring. In that these Stomas are intermingled, therefore this (earth) is covered with mingled plants and trees [5]. Those who knowing thus perform (the rite of) these (nights) have both offspring and cattle. These go imperfect to the world of heaven, for they resort to various Stomas; in that the Stomas are arranged in order, they go in order to the world of heaven, and there is order in both these worlds. These (nights) are thirty in number, the Viraj has thirty syllables; verily by the Viraj they win food. There are Atiratras on either hand, to secure food. Prajapati went to the world of heaven. But with whatever metre the gods yoked him, they achieved not him. They saw (the rite of) these thirty-two nights. The Anustubh has thirty-two syllables, Prajapati is connected with the Anustubh; verily having gained Prajapati by his own metre they mounted on him and went to the world of heaven.
