起信論疏筆削記 6.51

6.51

論　不相離者，意明不一不二。不一故二門各存，不二故唯是一心。以是一心故不相離，以不相離故能影攝，即反前責意也。

[On the Treatise's] "They are not separate": the meaning is to clarify that they are neither one nor two. Because they are not one, the two gates each persist; because they are not two, there is only the One Mind. Because it is the One Mind, they are not separate; because they are not separate, they can overshadow and subsume, which reverses the preceding reproof's intent.
