首楞嚴義疏注經 5.108

5.108

若執此根有實體者，即墮常見。若謂都無，成惡取空，諸佛不化。寧起有見如須彌山，不起空見如芥子許，以墮斷故。既左偏有相、右墮空門，空有二邊俱不見性，無明根結如何解除？故前偈云「汝觀交中性，空有二俱非。」故此二邊不能令脫。

If one grasps this faculty as having a real entity, one falls into the view of permanence. If one says it is completely nonexistent, it becomes the wrongly grasped emptiness, which the buddhas cannot transform. Better to give rise to a view of existence as vast as Mount Sumeru than to give rise to a view of emptiness the size of a mustard seed, because one falls into annihilationism. Since pulling to the left inclines toward the characteristic of existence and pulling to the right falls into the gate of emptiness, at both extremes of emptiness and existence one fails to see the nature; how then could the knotted root of avidyā be untied? Thus the previous verse says: "You should observe the nature within their intersection: both emptiness and existence are negated." Therefore these two extremes cannot bring about liberation.
