佛說佛名經 9.26

9.26

馬頭羅剎答曰：「此諸沙門受佛淨戒而不淨持，脚足不淨來行佛地、僧地；或乘驢馬遊行佛像門戶前而去，心無慚愧，以此罪故墮是地獄。」

The horse-headed rākṣasa replied, saying: "These śramaṇas received the Buddha's pure precepts but did not keep them purely; with unclean feet they walked upon the grounds of the Buddha and the Saṅgha; or they rode donkeys and horses, wandering past the doors and gates of Buddha images, with no shame in their hearts. Because of this sin, they have fallen into this hell."
