苾蒭（上毘逸反下測虞梵語草名也僧肇法師義苾蒭有四勝德一名淨乞食二名破煩惱三名能持戒四名能怖魔梵文巧妙一言具含四義故存梵言也）。

苾蒭 (Upper character: pí + yì [bì]; lower character: cè + yú [chū]. Sanskrit [bhikṣu], the name of a grass. According to Master Sengzhao's explanation, a bhikṣu possesses four supreme virtues: first, pure begging for food; second, destroying afflictions; third, ability to maintain the precepts; fourth, ability to terrify Māra. The Sanskrit formulation is so ingenious that a single word encompasses all four meanings, hence the Sanskrit term is retained).
