首楞嚴義疏注經 2.380

2.380

所亡之相通有八句：謂因緣也、自然也、是也、非也，此四是病。非因緣、非自然、非是、非非，此四是藥。經文從非因緣下三句，雙亡因緣、自然之藥病，謂非因緣、非自然，非不因緣、非不自然。不因緣義在自然中也。無非下二句，雙亡是非之藥病，謂無非、無不非，無是、無不是。藥病俱亡，無跡可滯，心行處滅，言語道斷，故云離一切相，以前諸相皆是虛妄遍計執故。

The characteristics to be dissolved comprise eight phrases in all: namely, causes and conditions, spontaneity, affirmation, and negation—these four are the sickness. Not causes and conditions, not spontaneity, not affirmation, and not negation—these four are the medicine. The three phrases in the sūtra text beginning from "neither cause nor condition" dissolve both the medicine and sickness of causes and conditions as well as spontaneity: namely, neither cause nor condition, nor spontaneity, nor non-cause and non-condition, nor non-spontaneity. The meaning of not being causes and conditions is contained within spontaneity. The two phrases beginning from "nor is there non-negation" dissolve both the medicine and sickness of affirmation and negation: namely, without negation, without non-negation, without affirmation, without non-affirmation. When both medicine and sickness are eliminated, there are no traces upon which to stagnate; the place of the mind's operation is extinguished, and the path of words is cut off. Therefore it is said: "it is free from all characteristics," because the preceding characteristics are all unreal and imagined natures.
