四分律行事鈔資持記 1.52

1.52

引示中，初科。言下文者，即五百結集文。彼明迦葉結集已，長老富那羅重更詰問結集次第，迦葉一一答已，彼云：我盡忍可，唯除八事親從佛聞憶持不忘。佛聽內宿內煮等。迦葉答言：實如汝所說，世尊以穀貴故聽；時世還豐，佛仍制斷。彼復言：佛是一切知見，不應制已還開，開已復制。（意云開制無定，則非一切知見。）鈔引迦葉答辭，仍易知見為智人耳。此明時有豐儉，不可一定；故興此教被及後世，即《了論》中時毘尼也。

In "citing and demonstrating", in the first section: The phrase "the text below" refers to the passage on the council of the five hundred. It explains that after Kāśyapa concluded the council, the elder Puṇya again interrogated him regarding the sequence of the council; after Kāśyapa answered each point, he said: "I completely assent, except for eight matters that I personally heard from the Buddha and remember without forgetting: the Buddha permitted keeping food indoors, cooking indoors, and so forth." Kāśyapa replied: "It is truly as you have said; the World-Honoured One permitted it because grain was dear; when times became abundant again, the Buddha prohibited it once more." He said again: "The Buddha is all-knowing and all-seeing; he should not have allowed an exception after prohibiting, and then prohibited again after allowing an exception." (The meaning is that if exceptions and prohibitions are not fixed, he is not all-knowing and all-seeing.) The Manual cites Kāśyapa's reply, yet changes "all-knowing and all-seeing" to "a person of wisdom". This clarifies that times have abundance and scarcity and cannot be fixed; therefore this teaching arose to extend to later generations, which is the "timely Vinaya" in the Vinayadvāviṃśatividyā-śāstra.
