大方廣佛華嚴經隨疏演義鈔 49.8

49.8

疏「瑜伽五十三百福行」，即決擇分中，文相甚顯。但少分者，經部許有分受，或多或全，由彼根性有劣中上差別，及持有多時少時等。少時從一日至十日，多時謂一年已去十年已來，盡壽可知。然其十種分為四類：初之三十，據事以分；次之三十，依時有分別；次之二十，約自他明；後之二十，依讚說立。正約行時名為百行，約所生福則為百福。若就十惡名為百非，謂少分殺等。

Regarding the commentary's "the hundred meritorious practices in the fifty-third fascicle of the Yogācārabhūmi": This is in the Decision Section (Viniścayasaṃgrahaṇī), where the textual marks are very clear. However, regarding the fractional [observance], the Sautrāntika allows taking the precepts partially, either more or completely, due to the inferior, middling, and superior differences in their faculties and nature, as well as holding them for a long time or a short time, and so forth. A short time is from one day to ten days; a long time is from one year to ten years; lifelong can be understood. However, the ten kinds are divided into four categories: the first thirty are distinguished based on matters; the next thirty are distinguished according to time; the next twenty are clarified in terms of oneself and others; and the final twenty are established based on praising and explaining. Directly in terms of the time of practice, they are called the hundred practices; in terms of the merit produced, they are the hundred merits. If considered in terms of the ten unwholesome actions, they are called the hundred faults, meaning fractional killing and so forth.
