俱舍論記 18.74

18.74

「唯餘百劫至九十一劫」者，釋第三句。謂三無數劫外，唯餘百劫造修非多。諸佛因中法應如是，皆百大劫修相異熟業。「唯薄伽梵」下，簡差別。聚落主，即是城主邑主。餘文可知。依說一切有部，出三無數劫修妙相業已去，方離四過失得二功德。

Regarding the passage from "Only a remaining hundred eons" up to "ninety-one eons": this explains the third line. That is to say, outside of the three incalculable eons, there remain only a hundred eons in which he creates and cultivates, which is not many. The causal state of all Buddhas is fundamentally like this: all cultivate the ripening karma of the marks for a hundred great eons. From "only the Bhagavān" downward distinguishes the differences. A village chief refers to a city lord or town magistrate. The rest of the text can be understood. According to the Sarvāstivāda, only after passing through the three incalculable eons and cultivating the karma of the wondrous marks does one abandon the four faults and attain the two virtues.
