成唯識論演祕 2.449

2.449

答：有二釋：一云，法爾、新熏隨其所應先業所引，正作因緣生現識者，依彼種立；二云，依二種立，共作因緣生第八識，勢力等故和合似一，不可說有體各別故，無二命失。有義斷云：今依前說，名言種子既有眾多，不可一切共生果故；然今命根所依之種，要前生熏，先業引故。

Answer: There are two explanations. One says: It is established based on whichever seeds—whether primordial or newly perfumed, as appropriate—are projected by prior karma and directly serve as the primary cause generating the active consciousness. The second says: It is established based on both kinds of seeds, which together serve as the primary cause generating the eighth consciousness; because their powers are equal, they blend as if into a single entity, and one cannot say they have distinct substances, so there is no fault of having two lives. One opinion determines: "Now we follow the former explanation; since seeds of names and concepts are numerous, it is impossible for all of them to jointly produce an effect; however, the seed upon which the life-faculty now relies must have been perfumed in a previous life, being projected by prior karma."
