The fiftieth sutta of the Majjhimanikāya. While Mahā-Moggallāna is living at Bhesakalāvana, Māra enters his belly and worries him. When Māra realises that Moggallāna has discovered him and can read his thoughts, he leaves his body and perches on the door bar of his cell. Moggallāna then addresses him and tells him how, once, he himself was a Māra named Dūsī, and roused the brahmin householders against Kakusandha Buddha and his disciples. As a result of this, Dūsī was born in Mahā-niraya (s.v. Avīci) and suffered great torments. Moggallāna warns Māra against assailing holy men lest he suffer a similar fate. Māra retires discomfited. M.i.332-8.
