"These are the thirty-three gods (the eight Vasus, the eleven Rudras, the twelve Adityas, Prajapati, and Vashatkara). I shall now recount their progeny according to their Pakshas, Kulas, and Ganas. The Rudras, the Saddhyas, the Maruts, the Vasus, the Bhargavas, and the Viswedevas are each reckoned as a Paksha. Garuda the son of Vinata and the mighty Aruna also, and the illustrious Vrihaspati are reckoned among the Adityas. The twin Aswins, all annual plants, and all inferior animals, are reckoned among the Guhyakas.
