Manu has enumerated twenty-one hells. It is situated below Patala and is a region of darkness, fear and terror. Its divisions are described, with the particular crime punished in them. Though the Sikh Scripture måkes the mention of Naraka of Hinduism and Dozakha of Islam, it presents its own interpretation of as many hells, as the births of transmigration. See : Dozakha.
