又有性者，安立有義，能持有義等者，示其正理。若於二種已下，重難。若於有無二種，但了有法不了無者，不應說意緣一切義，以但緣有故此違道理。

"Furthermore, an existent establishes the meaning of existence and can hold the meaning of existence, etc.": this reveals the correct reasoning. From "If with respect to the two kinds" downward, it raises a counter-objection: If, regarding the two kinds—existence and non-existence—it only cognized existent phenomena and did not cognize non-existence, one should not say that the mind takes all objects as its condition, because it would only take existence as its condition, which contradicts correct reasoning.
