瑜伽師地論略纂 11.143

11.143

論善士語中有五：第一、即毘奈耶因事制戒也；第三、四依謂乞食、糞掃衣、樹下坐、一切修善等；餘可知。

Where the treatise explains that speech of virtuous persons has five aspects: the first is the vinaya's formulation of precepts in accordance with circumstances; the third is the four reliances, meaning alms food, robes made of rags, sitting under trees, cultivating all good, and so forth; the rest can be understood.
