Atharva Veda 15.17

Paryāya the seventeenth

His out-breathing that is first, that is this earth.

His out-breathing that is second, that is the atmosphere.

His out-breathing that is third, that is the sky.

His out-breathing that is fourth, that is the asterisms.

His out-breathing that is fifth, that is the seasons.

His out-breathing that is sixth, that is they of the seasons.

His out-breathing that is seventh, that is the year.

The gods go about the same purpose (ártha); thus (etát) verily the seasons go about after the year and the Vrātya.

As they enter together into the sun (ādityá), just so [do they] also into new-moon day and full-moon day.

One [is] that immortality of theirs: to this effect (íti) [is] the offering.
