俱舍論記 6.49

6.49

「又一身中至因增上等」者，十位，謂胎內有五：一羯剌藍、二阿部曇、三閉尸、四揭南、五鉢羅奢佉；胎外有五：一嬰孩、二童子、三少年、四盛年、五老年。現身十位，後皆除前。若對餘未來身同類十位，一一皆與十位為因。《婆沙》十八，大有諸師解十位同類因，不能廣述。此論當一師不正義，故《婆沙》評家云「評曰：應作是說。餘身十位，一一皆與餘身十位及此身十位為同類因。此身十位，一一皆與此身十位及餘身十位為同類因。後位已生法與前位不生法亦為同類因故。」又解：此論亦同《婆沙》評家。此論現身十位，據現起說，故後位非前位因。若對餘未來身同類十位，一一皆與十位為因。若《婆沙》評家，現身十位，通據現起、不現起說，故此身十位望此身十位亦得為同類因等。應知十位但望同地、同趣而說，故《婆沙》一百三十一云「問：同趣、同地，處所差別，展轉相望為有因不？有說無因。此不應理，應有大種是剎那故。謂五淨居所有大種，無始生死曾未起故。」

On "Moreover, within one body [...] causal, empowering, and so forth": the ten stages refer to the five inside the womb: first, kalala; second, arbuda; third, peśī; fourth, ghana; fifth, praśākhā; and the five outside the womb: first, infancy; second, childhood; third, youth; fourth, prime of life; fifth, old age. In the ten stages of the present body, later ones all exclude earlier ones. But relative to the homogeneous ten stages of other future bodies, each and every one serves as a cause for the ten stages. In the Mahāvibhāṣā, fascicle 18, many masters explain the homogeneous cause of the ten stages, which cannot be elaborated in full. This treatise adopts the non-definitive doctrine of one master. Therefore, the critical arbiter of the Mahāvibhāṣā says: "Critical judgment: one should state it thus. Each and every one of the ten stages of another body serves as a homogeneous cause for the ten stages of another body and the ten stages of this body. Each and every one of the ten stages of this body serves as a homogeneous cause for the ten stages of this body and the ten stages of another body. This is because phenomena already arisen in a later stage also serve as homogeneous causes for unarisen phenomena in an earlier stage." Another explanation: this treatise also agrees with the critical arbiter of the Mahāvibhāṣā. The ten stages of the present body in this treatise are stated on the basis of actual arising; hence a later stage is not the cause of an earlier stage. But relative to the homogeneous ten stages of other future bodies, each and every one serves as a cause for the ten stages. In the case of the critical arbiter of the Mahāvibhāṣā, the ten stages of the present body are stated comprehensively in terms of both arising and non-arising; hence the ten stages of this body with respect to the ten stages of this body can also serve as homogeneous causes and so forth. One should know that the ten stages are spoken of only with respect to the same plane and the same destiny. Therefore, the Mahāvibhāṣā, fascicle 131, says: "Question: In the same destiny and same plane, with differences of location, are they mutually causes or not? Some say there is no cause. This is not logical, for there would be great elements that are momentary, meaning that the great elements belonging to the Five Pure Abodes have never arisen from beginningless saṃsāra."
