俱舍論疏 9.170

9.170

「論曰至因果性故」，釋頌文也。此十二支能生後義名之為因，此因為緣能起後果故名緣起，從前生義名之為果。此果皆從緣所生故，名緣已生。如是一切十二支皆有因果義，故緣起、緣已生二義皆成。

The commentary states: 'Up to: because of the nature of cause and effect': this explains the verse. That these twelve limbs can give rise to subsequent ones is the meaning of 'cause'; because this cause serves as a condition to originate subsequent effects, it is called 'conditioned origination' (pratītyasamutpāda). The meaning of arising from previous ones is 'effect'; because all these effects arise from conditions, they are called 'conditionally arisen' (pratītyasamutpanna). In this way, all twelve limbs have both the meaning of cause and effect, and therefore both designations—'conditioned origination' and 'conditionally arisen'—are established.
