瑜伽論記 19.14

19.14

言自性淨，謂恭敬隨學，具分隨學者，即是受持戒令戒淨，尊重珍敬婆羅提木叉，如佛住世名恭敬隨學，於所受中多小皆獲故名具分隨學。

Regarding the statement "purity of intrinsic nature, which means respectfully training in accordance [with the precepts] and training completely in accordance [with them]": this means upholding the precepts to make the precepts pure. Respecting and treasuring the prātimokṣa as if the Buddha were residing in the world is called "respectfully training in accordance." Gaining all of what has been received, whether much or little, is called "training completely in accordance."
