Sūta said: The Prajāpati (Lord of the subjects) who was creating at the outset the fourfold set viz.: the Devas, the sages, the Pitṛs and the human beings, created the living beings-both mobile and immobile. After creating Yakṣas, the Piśācas, the Gandharvas, the Apsaras, the human beings, the Kinnaras, the Rākṣasas, the birds, the animals, the deer and the serpents, he created the Avyayas (changeless ones) and Vyayas (the changeables) as well as the mobile and the immobile beings.
