首楞嚴義疏注經 8.47

8.47

由前起後也。清禁既圓，觀行成就，於六塵境已知虛幻，終不信任隨流奔逸，妄有取著。

"This is the arising of the subsequent based on the preceding. Once the pure prohibitions are complete and the contemplative practice is accomplished, one already knows that the sphere of the six dusts is illusory, and in the end will never let oneself run astray following the flow, falsely grasping or clinging."
