6.187

損減等者。謂執有是增益過，執無是損減過，今既一向離相，正當此句。斯則於果損福德莊嚴，於因損五度之行，壞俗諦也。

"Diminution..." and so forth: grasping at existence is the fault of superimposition; grasping at non-existence is the fault of diminution. Now, being exclusively detached from marks corresponds precisely to this clause. This diminishes the adornment of merit in terms of the fruit, and diminishes the practice of the five pāramitās in terms of the cause, destroying conventional truth.
