俱舍論記 12.28

12.28

「如彼經言至三劫無數」者，引經答。阿僧企耶，第五十二，於此六十數中其一。至論主出世，現有前五十二，諸傳誦者忘失後八。若數大劫至此六十數中，第五十二阿僧企耶名劫無數。此劫無數，復積至三，經中說為三劫無數。非諸算計不能數知，故得說為三劫無數。《婆沙》一百七十七云「總有七說。」此論當第三說，廣如彼釋。

"As that sūtra states [...] three kalpa-asaṃkhyeyas" answers by citing a sūtra. Asaṃkhyeya is the fifty-second, one among these sixty numbers. By the time the author of the treatise appeared in the world, the first fifty-two were extant, while the reciters had forgotten the last eight. If one counts great kalpas up to the fifty-second among these sixty numbers, it is called a kalpa-asaṃkhyeya. When this kalpa-asaṃkhyeya is accumulated to three, it is described in the sūtras as three kalpa-asaṃkhyeyas. It is not that reckoning calculations are unable to count and know it; thus it can be called three kalpa-asaṃkhyeyas. The Vibhāṣā, fascicle 177, states: "Altogether there are seven explanations." This treatise corresponds to the third explanation, as fully explained therein.
