大乘義章 2.14

2.14

重無相者，先以無學等見之智，觀彼滅下盡止妙出，直名無相。後觀此智盡滅之處非數無為亦是寂止，擊彼聖道，名無相無相。何者智盡非數無為？云何擊乎？觀滅之智應起不起，是其智盡，非數無為。欲擊彼智，先觀煩惱不起之處，數滅無為是其寂止。是寂止故，可願可樂。以此寂止可願樂故，所滅煩惱是可厭惡。後觀此智不起之處，非數無為亦是寂止，可願可樂，與數滅同。以智盡處同彼數滅可願樂故，所滅之智與彼煩惱同可厭惡，擊之如是。問曰：何故不以妙出擊彼聖道，偏用止行？釋言：非數非妙出故。何故不以滅行擊之？以此濫同無常滅故。

Regarding repeated signlessness: one first observes destruction, pacification, excellence, and departure under cessation with the wisdom of the view of the non-learner and the like, which is straightforwardly called signlessness. Afterward, one observes that the locus where this wisdom is completely destroyed is non-analytical cessation (apratisaṃkhyā-nirodha), which is also tranquil pacification; striking at that holy path, this is called signlessness-signlessness. What is wisdom's destruction as apratisaṃkhyā-nirodha? How does it strike? When the wisdom contemplating cessation ought to arise but does not arise, that is its wisdom's destruction, apratisaṃkhyā-nirodha. Intending to strike at that wisdom, one first observes the locus where defilements do not arise: analytical cessation (pratisaṃkhyā-nirodha) is its tranquil pacification. Because it is tranquil pacification, it is to be wished for and delighted in. Because this tranquil pacification is to be wished for and delighted in, the defilements that were destroyed are to be revulsed from and detested. Afterward, one observes the locus where this wisdom does not arise: apratisaṃkhyā-nirodha is also tranquil pacification, to be wished for and delighted in, identical with analytical cessation. Because the locus of wisdom's destruction is, like analytical cessation, to be wished for and delighted in, the destroyed wisdom is, like those defilements, to be revulsed from and detested; striking at it is like this. Question: Why is the holy path not struck at with excellence and departure, using the practice of pacification alone? Explanation: Because apratisaṃkhyā is not excellence or departure. Why is it not struck at with the practice of destruction? Because this would be confounded with impermanent destruction.
