佛說觀佛三昧海經 8.19

8.19

"The elder Rulüda, seeing that the Buddha had transformed the evil women of Māra, praised him, saying: 'Excellent, excellent! In the past, the Tathāgata crushed Pāpīmān's army; now his conversion of these women is no different from the original [victory]. When this mark is displayed, immeasurable gods bring forth bodhicitta.' Among the troops brought by King Prasenajit, five hundred men asked the Buddha to go forth [into homelessness]. Their beards and hair fell off naturally, the clothes they wore transformed into kāṣāyas, and they immediately attained the path of arhatship. At that time, in the great assembly, those who rejoiced at the sight of the sheath of the horse king eliminated the sins of fifty billion kalpas of birth and death; they paid homage to the Buddha and withdrew."
