9.181

何以故？由彼故空，彼實是無等者，景云：謂由遍計所執虛誑故空彼實是無，於此離言法性依他起等無虛誑說為空此實是有，由此道理可說為空。若說離言自性亦都無者，倒情計執必有依託，依託何處而得起耶？故云何處，若有依託，即有能依所依，於此二何者是空，故云何者。若言能依所依二俱空者，能依虛妄可說為空，所依真實何故名空，亦不應言由此所依故能依虛妄，能依空故於此所依亦說為空。

Regarding "Why is this so? Empty by means of that, that is truly non-existent, and so forth": Jing says: It means that being deceptive, the imagined nature is empty, and that is truly non-existent; upon this ineffable dharmatā, the other-dependent and so forth, it is without deception and said to be empty, and this is truly existent. By this principle it can be said to be empty. If one says that even the ineffable intrinsic nature does not exist at all, the conceptualized grasping of the inverted mind must have something to rely upon; relying upon what place could it arise? Hence it says "what place." If there is something relied upon, there is that which relies and that which is relied upon; of these two, which one is empty? Hence it says "which one." If one says that both that which relies and that which is relied upon are empty: that which relies is false and can be said to be empty; why should that which is relied upon, being real, be called empty? Nor should one say that because of this that is relied upon, that which relies is false, and because that which relies is empty, this that is relied upon is also said to be empty.
