俱舍論疏 12.66

12.66

「論曰至諸佛出現」，明佛出時，八萬歲漸減，不剋定時。即上八萬歲減半年等，皆容出世。下至百年，百年已下無容佛出。准《賢劫經》第十云「拘留孫佛人壽四萬歲時出世，拘那含牟尼佛人壽三萬歲時出世，迦葉佛人壽二萬歲時出世，釋迦牟尼佛人壽百歲時出世。」准《西域記》第六卷云「六萬、四萬、二萬、百歲，佛出世也。」又准《立世經》第九云「二十小劫世界起成，已住者幾多已過、幾多未過？八小劫已過，十一小劫未來，第九一劫現在未盡。」准此經文，即今正當第九劫，即賢劫中四佛出世，以俱在此第九劫漸減位。應更詳檢。准此文，即前八劫中無佛出世，彌勒佛即當第十劫出。又准《彌勒經》八云「劫」，是刀兵劫。經云「於刀兵劫中，乃至今生此。」又准此文，後唯有十一劫，更有九百九十六佛出，時恐太促。詳其賢劫，似是風劫，於六十四劫中此為第一劫。總六十四劫為一賢劫，於中千佛理且可然。應更詳檢。

On "The Śāstra says... Buddhas appear": Explaining the time of a Buddha's appearance: during the gradual decrease from eighty thousand years, with no fixed time. That is, from eighty thousand years downward, decreasing by half a year and so forth, an appearance in the world is always possible, down to one hundred years; below one hundred years, there is no possibility of a Buddha's appearance. According to the Bhadrakalpika-sūtra, fascicle 10, it says: "Krakucchanda Buddha appeared in the world when human lifespan was forty thousand years; Kanakamuni Buddha appeared in the world when human lifespan was thirty thousand years; Kāśyapa Buddha appeared in the world when human lifespan was twenty thousand years; Śākyamuni Buddha appeared in the world when human lifespan was one hundred years." According to the Xiyu ji, fascicle 6, it says: "At sixty thousand, forty thousand, twenty thousand, and one hundred years, Buddhas appear in the world." Furthermore, according to the Lokasthāna-sūtra, fascicle 9, it says: "In the twenty small kalpas of the world's arising and formation, of those that have abided, how many have passed and how many have not passed? Eight small kalpas have passed, eleven small kalpas are in the future, and the ninth kalpa is currently not yet finished." According to this scriptural passage, right now precisely corresponds to the ninth kalpa; that is, the four Buddhas of the Bhadrakalpa who have appeared in the world are all within the gradually decreasing period of this ninth kalpa. This should be further examined in detail. According to this text, then within the preceding eight kalpas no Buddha appeared in the world, and Maitreya Buddha will appear precisely in the tenth kalpa. Furthermore, according to the Maitreya-sūtra [fascicle] 8, the "kalpa" mentioned is the kalpa of weapons; the sūtra says: "Within the kalpa of weapons, down to being born here today." Furthermore, according to this text, afterwards there are only eleven kalpas remaining, yet nine hundred and ninety-six more Buddhas are to appear; the time is feared to be far too pressed. Examining the Bhadrakalpa, it seems to be a wind kalpa, and among the sixty-four kalpas, this is the first kalpa. Taking sixty-four kalpas as one Bhadrakalpa, within which a thousand Buddhas [appear], would for the moment be plausible in principle. This should be further examined in detail.
