成唯識論掌中樞要 2.236

2.236

依他起無自然生者，自然有二：一、無因自然生，舉此攝一切無因；二、以自然為因生，舉此攝一切冥性等不平等因生。無此無因自然及無不平等因自然生，故名自然無生。依他起中亦有無因、惡因，非一橫執，何故唯遮自然生耶？答：且舉自然，餘不平等因皆是此收。此說三無性，破非餘增益。餘損減門三性所違，故非破無因。

That the dependent nature has no spontaneous arising has two meanings: first, uncaused spontaneous arising, mentioning this subsumes all that is uncaused; second, arising with spontaneity as a cause, mentioning this subsumes all arising from unequal causes such as the unmanifest primal nature (pradhāna). Because there is neither this uncaused spontaneous arising nor this spontaneous arising from an unequal cause, it is called 'spontaneously unarisen'. In the dependent nature, there are also uncaused and evil causes, which are multiple perverse attachments; why does it solely refute spontaneous arising? Answer: For now, it mentions spontaneity, and other unequal causes are all subsumed under this. This discussion of the three naturelessnesses refutes [attachments], not other superimpositions. The remaining approach of underestimation is contradicted by the three natures; therefore, it does not refute the uncaused.
