大乘百法明門論開宗義決 1.117

1.117

餘八識聚三界九地乃至文云故皆得作等無間緣等者。謂第八識三界九地皆容互作等無間緣。下上死生相開導故。有漏無間有無漏生。無漏定無生有漏者。鏡智起已更無斷故。若與無記相望亦然。若第七識三界九地亦容互作等無間緣。隨第八識生處繫故。有漏無漏容互相生。十地位中得相引故。善與無記相望亦然。第六意識三界九地有漏無漏善不善等各容互作等無間緣。潤生位等更相引故。若五識中。眼耳身識欲色二界。鼻舌二識唯欲界地。自類互作等無間緣。三性相望應知亦爾。有漏得與無漏開避。無漏不與有漏導引。事智起已必不斷故。

Regarding the passage "the aggregation of the remaining eight consciousnesses, throughout the three realms and nine stages, up to, therefore are all able to serve as immediately preceding conditions": the eighth consciousness across the three realms and nine stages can mutually serve as an immediately preceding condition, because death and rebirth between lower and higher stages open the way and guide one another. An unoutflowing consciousness arises immediately after an outflowing one; an outflowing consciousness definitely cannot arise from an unoutflowing one, because once the mirror-like wisdom arises, it is never interrupted. Looking across to the indeterminate, it is also like this. The seventh consciousness across the three realms and nine stages can also mutually serve as an immediately preceding condition, bound to the place of birth of the eighth consciousness; outflowing and unoutflowing can mutually produce each other, because they can induce each other within the ten stages (daśabhūmi); wholesome looking across to indeterminate is also like this. The sixth mental consciousness across the three realms and nine stages, whether outflowing or unoutflowing, wholesome or unwholesome, can each mutually serve as an immediately preceding condition, because in the state of moistening rebirth, etc., they induce one another. Among the five consciousnesses, the visual, auditory, and tactile consciousnesses belong to the kāma- and rūpa-dhātu, while the olfactory and gustatory consciousnesses belong solely to the kāma-dhātu; within their own categories they mutually serve as immediately preceding conditions. Looking across the three moral natures should also be understood in this way. The outflowing can yield place to the unoutflowing; the unoutflowing does not guide the outflowing, because once the all-accomplishing wisdom arises, it is definitely never interrupted.
