32.23

The *New Vibhāṣā Śāstra* states: From the southern continent down to Avīci is forty thousand yojanas in total. It is pointed at the top and broad at the bottom, like a heap of grain. The *Sarvāstivāda Śāstra* states: Beneath the southern continent are five hundred yojanas of earth and mud, and five hundred yojanas of white clay. The seven hells from Sañjīva to Pratāpana are altogether nineteen thousand yojanas in height, each ten thousand yojanas in breadth. Avīci is twenty thousand yojanas in height and breadth. The *Abhidharma Śāstra* states: The lifespan in Sañjīva is five hundred years; in Kālasūtra, one thousand years; in Saṃghāta, two thousand years; in Raurava, four thousand years; in Mahāraurava, eight thousand years; in Tapana, sixteen thousand years; in Pratāpana, half a kalpa; in Avīci, one kalpa. The *Abhidharmakośa Śāstra* states: One day and night in Sañjīva equals five hundred years of the Cāturmahārājakāyika heaven, and so on sequentially until Tapana, where one day and night equals sixteen thousand years of the Paranirmitavaśavartin heaven (the remaining hells correspond sequentially by analogy). The *Tattvasiddhi Śāstra* states: The five kinds of 'uninterrupted' (Avīci) are: first, uninterrupted fruition of the destiny, because one is reborn there immediately upon relinquishing the body; second, uninterrupted suffering, because there is no pleasure in between; third, uninterrupted time, because it is fixed at one kalpa; fourth, uninterrupted life, because it is not severed midway; fifth, uninterrupted form, for this hell is eighty thousand yojanas in length and breadth, yet it is full with a single person and equally full with many persons (*Sarvāstivāda Śāstra* says twenty thousand yojanas).
