成唯識論演祕 6.631

6.631

詳曰：按《瑜伽論》，十二有支分，因果雜如前具明。受支名雜，以觸為因名為因受；與愛為緣名為果受，前際果故。由受二別故此文起，豈容無義徒致煩文？以凡凌聖竊為未可。

Detailed commentary: According to the Yogācārabhūmi, the twelve branches of existence are divided into cause and effect in a mixed manner, as fully clarified earlier. The feeling branch is called mixed because taking contact as its cause it is called causal feeling, and serving as condition for craving it is called fruit feeling, being the fruit of the prior limit. Because of the two distinctions of feeling, this text arises; how could it be without meaning, needlessly causing superfluous text? Using the worldly to demean the holy is privately considered impermissible.
