79.74

疏「心中非有意」下，四明不即不離故難顯說。於中三：初約八識心王辯、二王所對辯、三一一結例。言非有者，是不即義，二相別故。亦非不有，是不離義，無二體故。又非有者，以無二體，互攝盡故。亦非不有者，二俱不壞，力用交徹故。

Regarding the commentary's statement, "In the mind there is no thought..." downward: this is the fourth part, showing that being neither identical nor separate makes it difficult to express. Within this are three: first, discerning in terms of the mind-kings of the eight consciousnesses; second, discerning in contrast with the mental factors; third, concluding each by analogy. Saying "not existent" means non-identity, because their two marks are distinct. Saying "nor nonexistent" means non-separation, because they do not have two essences. Furthermore, "not existent" is because, having no two essences, they mutually subsume each other entirely. "Nor nonexistent" is because neither is destroyed, their power and function mutually interpenetrating.
