四分律行事鈔資持記 2.162

2.162

多宗中，初科。文列三種，竝異《四分》。言不重發者，三戒永定，如下心受五，中心受十；本俗仍下，餘五方勝，中心受十，上心受大，亦爾。彼云：木叉戒者，無有重得；若微品心，受得五戒；後以中上品心受十戒，先得五戒，更無增勝；於後五戒，乃得增耳。不重受者，彼計一受即定；既不重發，更受不增，故不立也。準下但明具戒，意詳五八十亦爾。以五制盡形，八限日夜，縱逐日受，望當日中，不可重故。不重犯者，此據初篇同種為言。依本定者，本，謂壇場初受也。故下，引證。《婆沙》中，年少苾芻，得上品戒，以能起上品心受故；羅漢苾芻，得下品戒，以先發下品心受，後不增勝故。問：羅漢既發定共道俱，豈得不增；戒必不增，那得聖道？如是思之。

In the Sarvāstivāda School, the first section: the text lists three kinds, all differing from the Dharmaguptaka. As for "not generating anew," the three [grades of] precepts are permanently fixed; like receiving the five with an inferior mind, and receiving the ten with a middling mind—the original secular [five] remain inferior, and only the remaining five are superior; receiving the ten with a middling mind and receiving the great [precepts] with a superior mind is also like this. It says: as for the prātimokṣa precepts, there is no obtaining them anew; if with a minimal-grade mind one receives and obtains the five precepts, and later with a middling or superior-grade mind receives the ten precepts, the previously obtained five precepts do not increase in superiority; only with respect to the latter five precepts does one obtain increase. As for "not re-receiving," that school posits that a single reception is fixed; since they are not generated anew, receiving them further does not increase them, hence it is not posited. Although the text below only clarifies the full precepts, the intent applies similarly to the five, eight, and ten. Because the five are prescribed for the duration of life, and the eight are limited to a day and night, even if received day by day, viewed within that single day, they cannot be re-received. As for "not re-violating," this is stated based on the same class in the first chapter [pārājika]. Relying on the original determination: "original" refers to the initial reception on the platform. Hence, it is cited below as proof. In the Mahāvibhāṣā, a young bhikṣu obtains the superior-grade precepts because he is able to arouse a superior-grade mind to receive them; an arhat bhikṣu obtains the inferior-grade precepts because he previously generated an inferior-grade mind to receive them, and later they do not increase in superiority. Question: Since an arhat has generated the concentration-concomitant and path-conjoined, how could they not increase? If the precepts definitely do not increase, how could he attain the noble path? Contemplate this in this manner.
