17.51

第五明食肉之人皆是過去曾作惡羅剎。由習氣故今故貪肉。是故不應食肉也。如彼經說。有諸眾生。過去曾修無量因緣。有微善根得聞我法。信心出家在我法中。過去曾作羅剎眷屬。虎狼師子猫狸中生。雖在我法食肉餘習。見食肉者歡喜親近。入諸城邑聚落塔寺。飲酒噉肉以為歡樂。諸天人觀如羅剎爭噉死屍。等無有異。而不自知。已失我眾成羅剎眷屬。雖服袈裟剃除鬚髮。有命看見心生恐怖。如畏羅剎。此明食肉皆是過去曾作羅剎。師子虎狼猫狸中來。故應裁斷也。

Fifth, explaining that those who eat meat were all evil rākṣasas in the past; because of their conditioning (vāsanā), they still crave meat now. Therefore, one should not eat meat. As that sūtra says: 'There are sentient beings who in the past cultivated immeasurable causes and conditions, and with slight wholesome roots get to hear my Dharma and with faithful minds go forth into homelessness (pravrajyā) within my Dharma. Having in the past been the kin of rākṣasas, or born among tigers, wolves, lions, and cats, although they are now within my Dharma, due to the residual conditioning of meat-eating, when they see those who eat meat they are delighted to draw close to them. They enter cities, towns, hamlets, stūpas, and monasteries, drinking alcohol and devouring meat, taking this as joy and delight. When devas and humans look upon them, they are no different from rākṣasas fighting over and devouring corpses. Yet they do not know it themselves: they have already fallen from my assembly and become the kin of rākṣasas. Although they wear the kāṣāya and have shaved their hair and beards, when living beings see them, fear arises in their minds just as if dreading rākṣasas.' This explains that meat-eaters all come from having previously been rākṣasas, lions, tigers, wolves, and cats; therefore, one should cut it off.
