肇論新疏 1.34

1.34

約起滅釋也。初二句明相因而起。但起一見，一見隨生，如見牛有角謂兔無角等。故《密嚴》云：「要待於有法而起於無見。」此所治之病也。後二句明相因而滅。苟治一見一見隨亡，經中既云非有，故亦非無。故《密嚴》云：「有法本自無，無見何所待。」此能治之藥也。偉哉！善巧曲盡經旨。

This is explained in terms of arising and ceasing. The first two phrases clarify arising by mutual dependence: once a single view arises, the other view arises following it, just as seeing that a cow has horns makes one say a rabbit has no horns, and so forth. Hence the Ghanavyūhasūtra says: "It is only depending on existent dharmas that a view of non-existence arises." This is the disease to be cured. The latter two phrases clarify perishing by mutual dependence: if one cures one view, the other view perishes along with it. Since the sūtra already says "not existent", it is therefore also "not non-existent". Hence the Ghanavyūhasūtra says: "Existent dharmas are fundamentally non-existent of themselves; what could the view of non-existence depend on?" This is the medicine that can cure it. How grand! Skillfully exhausting the sūtra's purport in every detail.
