四分律行事鈔資持記 2.1468

2.1468

生草淨水，立大小便，三戒。（並譏云如猪狗駱駝牛驢等。）從初至此五十一戒，明敬僧威儀。（文列四十一，并衣纏頸下十條，各有白衣舍坐。）

The three precepts against defecating or urinating upon living grass or into pure water while standing. (All censured with, 'Like pigs, dogs, camels, oxen, donkeys, and so forth.') From the beginning down to this, fifty-one precepts explain the deportment of venerating the Saṅgha. (The text lists forty-one, plus the ten items under wrapping the neck with robes, each involving sitting in a layperson's house.)
