佛祖統紀 1.86

1.86

述曰。世言七佛者。准藥王經。過去莊嚴劫千佛。始自華光。終毘舍浮。現在賢劫。始俱留孫。終於樓至。是知毘婆尸至毘舍浮三佛。皆在過去莊嚴劫。拘留孫至釋迦四佛。皆現在賢劫。七佛前後相繼。止隔一劫。今諸經多言毘婆尸在九十一劫。餘二佛在三十一劫相去遠甚。似不在莊嚴劫之數。然三祇滿時。正值毘婆尸。自此百劫種相好。則九十一劫。於說自合。蓋除前讚佛超越九劫故耳。如上兩義。雖是方便分別。然恐此土翻譯。部別不同。今姑並存。以為援文者之證（校閱者云。若謂七佛前後相繼。止隔劫一者。則應毘婆尸佛。當記過六劫而得成佛。乃至迦葉佛。當記過一劫。而得成佛。何謂百劫種相好則九十一劫於說自合。下文又云。已上四佛。在賢劫中。第九減劫。相繼出世。俱與止隔一劫之言相違。覽者詳之）。

The commentary states: Regarding the Seven Buddhas spoken of conventionally, according to the Bhaiṣajyarāja-sūtra, the one thousand Buddhas of the past Glorious Kalpa begin with Padmaprabha and end with Viśvabhū; the present Auspicious Kalpa begins with Krakucchanda and ends with Ruci. Thus we know that the three Buddhas from Vipaśyin to Viśvabhū were all in the past Glorious Kalpa, while the four Buddhas from Krakucchanda to Śākya are all in the present Auspicious Kalpa. The Seven Buddhas succeeded one another, separated by only a single kalpa. Now, most scriptures say that Vipaśyin was ninety-one kalpas ago and the other two Buddhas were thirty-one kalpas ago, which are very far apart, seemingly not part of the count of the Glorious Kalpa. However, when the three asaṃkhyeyas were completed, he precisely encountered Vipaśyin; planting the marks and signs for one hundred kalpas from that point onward, the ninety-one kalpas naturally harmonises with the explanation, because it deducts the nine kalpas surpassed by previously praising the Buddha. Although the above two explanations are expedient distinctions, fearing that the various schools among the translations in this land differ, we preserve both for now to serve as evidence for those who cite the texts. (The reviewer says: 'If it is asserted that the Seven Buddhas succeeded one another, separated by only a single kalpa, then Vipaśyin Buddha should have predicted attainment of Buddhahood after six kalpas, and likewise Kāśyapa Buddha should have predicted attainment of Buddhahood after one kalpa. Why say that planting the marks and signs for one hundred kalpas naturally harmonises with the ninety-one kalpas? The text below also says: "The four Buddhas above appeared successively during the ninth decrement kalpa of the Auspicious Kalpa," both of which contradict the claim of being separated by only a single kalpa. Readers should examine this carefully.')
