答：由空為門遣能、所取，方泯二相而能證理。從所由門名空顯理，理亦無失。有云：若也執空，亦說為有；從多執有，此說為空。

Answer: Because emptiness is the gateway to dispel the grasper and the grasped, only then are the two marks extinguished and one can realize the principle.

Some say: if one also grasps at emptiness, it is also spoken of as existence; but because the majority grasp at existence, here it is spoken of as emptiness.
