梵網經古迹記 2.89

2.89

言「斷大慈悲性種子」者，由食至殺故。言「見而捨去」者，鷹逐之鴿，於鶖子影未解其惶，況乎在食之位。言「食肉得無量罪」者，如《一切智光明仙人不食肉因緣經》中，廣顯食之失。彼仙人即是彌勒，當成佛時制食肉犯重，具如彼說。

Regarding 'severing the seed of the nature of great compassion': this is because eating leads to killing. Regarding 'seeing [him], they flee': even a dove pursued by a hawk did not lose its terror under Śāriputra's shadow; how much more so in the position of one who eats them? Regarding 'eating meat brings boundless offenses': as in the Sūtra on the Causes and Conditions of the Omniscient Brightness Sage Not Eating Meat, it extensively illustrates the faults of eating it. That sage was Maitreya himself; when he attains Buddhahood, he will prohibit meat-eating as a major offense, fully as explained therein.
