15.256

基云：先要由欲界起故，後生色界後起。以攝色界一生故，欲界所入定是後報業。若色界更不入定，但於餘地一生而便受報，欲界之定可成後報。於色界中，更後入定，明知此人先於欲界已是退人。若不退者，何故於色界異地而更起定？故知以色界等更起定方受報，及欲界不退人此定當知唯是生報。

Ji says: It must first be aroused from the desire realm; later, being born in the form realm, it is aroused later. Because it encompasses one lifetime in the form realm, the concentration entered in the desire realm is karma of subsequent retribution. If one does not enter concentration again in the form realm, but merely experiences retribution for one lifetime in another stage, the concentration of the desire realm could become subsequent retribution. If one enters concentration again later in the form realm, one clearly knows that this person had already regressed previously in the desire realm. If they had not regressed, why would they arouse the concentration again in a different stage, the form realm? Therefore, we know that only by arousing concentration again in the form realm, etc., does one experience retribution; and for a person of the desire realm who does not regress, this concentration should be known to be solely retribution upon rebirth.
