成唯識論演祕 3.211

3.211

答：按《瑜伽論》五十一云：由五因故，一、謂賴耶識先世所造業行為因，眼等轉識現緣為因，謂根、境等。二、六識三性可得。三、六識無覆無記，異熟所攝，類不可得。四、六識別依於彼彼，依彼彼識轉，即彼所依應有執受，餘無執受。設許執受亦不應理，識遠離故。五、又所依止應成數數執受過失，所以者何？由彼眼識於一時轉，一時不轉，餘識亦爾，第八異彼故能執受。

Answer: According to Fascicle 51 of the Yogācārabhūmi: Due to five causes. First, because the ālaya consciousness has as its cause the actions created in previous lifetimes, whereas the evolving consciousnesses such as the eye [consciousness] have present conditions as their causes, namely the faculties, spheres, and so forth. Second, the six consciousnesses are found to have the three natures. Third, the six consciousnesses are non-obscured and indeterminate, subsumed under retribution, whose homogeneous continuity cannot be maintained. Fourth, the six consciousnesses individually depend on their respective bases and evolve depending on their respective consciousnesses; thus those bases would have appropriation, while the rest would lack appropriation. Even if appropriation were admitted, it would not be logically sound, because the consciousnesses become separated. Fifth, furthermore, there would be the fault that their bases would repeatedly undergo appropriation. Why is this? Because that eye consciousness evolves at one time and does not evolve at another time, and the other consciousnesses are likewise; the eighth is different from them, and therefore it is capable of appropriation.
