mānuṣaṃ prāpya kubjo vā kutsito vāmano 'pi vā /
caṇḍālapukkasādyāsu naro yoniṣu jāyate //

“When he has thus passed over a thousand yojanas he is released, and then enters another similar hell Niraya,[9] to purge away his sins. Afterwards when he has passed through all the hells, the sinner enters the brute creation, among worms, insects and birds; among carnivorous animals; among mosquitoes and such like. After having been born among elephants, trees and such like, among cattle, and among horses also; and among other evil and noxious creatures; he attains humanity, and is born a man, contemptible as a hunch-back or a dwarf; among caṇḍālas, pukkasas and such-like castes; and then accompanied by the remainder of his sin and merit, he enters the castes in ascending order, such as sūdras, vaiśyas, kings and so on; also the position of brāhmans, the gods and Indra. Sometimes in descending order, and thus evil-doers fall headlong into the hells.
