In Buddhism
Mahayana (major branch of Buddhism)
Source: Wisdom Library: Maha Prajnaparamita SastraKṛṣṇatvac (कृष्णत्वच्) refers to “one having a black skin”, according Mahāprajñāpāramitāśāstra (chapter XLVI).—There are two kinds of Pretas: lecherous Pretas and emaciated Pretas (kṣutkṣāma). The lecherous Pretas enjoy happiness like the gods but they live with the starving Pretas of whom they are the leaders. The starving Pretas have an enormous belly (sthūlodara) like a mountain, a mouth like the eye of a needle (sūcimukha) and consist of three things: a black skin (kṛṣṇatvac), tendons (snāyu) and bones (asthi). For innumerable hundreds of years, they have not even heard the words “food and drink” (annapāna), still less have they seen their shapes.

Mahayana (महायान, mahāyāna) is a major branch of Buddhism focusing on the path of a Bodhisattva (spiritual aspirants/ enlightened beings). Extant literature is vast and primarely composed in the Sanskrit language. There are many sūtras of which some of the earliest are the various Prajñāpāramitā sūtras.
