The Pravargya, indeed, is the year; for the year is everything, and the Pravargya is everything: when it is placed on the fire then it is spring; when it is burning-hot then it is summer; when it is flowing over then it is the rainy season;--but, indeed, when the rains overflow, all the gods and all beings subsist thereon; and, verily, the rains overflow for him who thus knows this.
