四分律行事鈔資持記 1.242

1.242

無難中，初示不定。疏云諸部皆云一拘盧舍，而互說不定；大則二千弓，弓長五肘（出《僧祇》，計十里。）；小則五百弓，弓長四肘（出《十誦》，計六百步為二里。）。注引《了疏》，翻同本律；然鼓有大小，聲有遠近，亦不可準。雜下，明今取。彼經云一拘屢奢，注云秦言五里。

In [the section on] without difficulties, first it shows that it is unfixed. The Commentary states: all the schools say one krośa, yet their explanations vary and are unfixed; the larger is two thousand bows, each bow being five forearms long (found in the Mahāsāṃghika-vinaya, calculated as ten leagues); the smaller is five hundred bows, each bow being four forearms long (found in the Daśādhyāya-vinaya, calculated as six hundred paces, which is two leagues). The note cites the Liaoshu, where the translation matches our vinaya; however, drums have large and small sizes, and sounds travel near and far, so it also cannot be standardized. From "Za" onwards, it clarifies what is adopted now: that sūtra says one krośa, and the note says: the language of Qin says five leagues.
