彰所知論 2.8

2.8

約兩重因果者有二，一前際、二後際。前際者，謂無明是惑、行即是業，彼二因支；由彼所生識等五支，即是果支，一重因果。現在愛取二支是惑、有即是業，三當來因；由彼所生，當生老死，即是果支，一重因果。如是十二有支，兩重因果。

According to the two layers of cause and effect: there are two, first the prior period, and second the posterior period. As for the prior period: ignorance is defilement and formations are karma, which are the two causal links; the five links from consciousness onward produced by them are the fruition links: this is one layer of cause and effect. The two present links of craving and grasping are defilements and becoming is karma, which are the three causes of the future; birth and old age and death produced by them in the future are the fruition links: this is one layer of cause and effect. Thus, the twelve links of existence are two layers of cause and effect.
