仁王護國般若波羅蜜多經疏 2.36

2.36

解曰：言散空者，謂有放有棄、有捨可得，此散由散空。彼經次云「無變異空」，謂無放無棄、無捨可得，此無變異由無變異空。前有後無，相對相故。此雖闕無，義影對故。言本性空者，謂一切法本性，若有為法性、若無為法性，皆非聲聞獨覺菩薩如來所作亦非餘所作，此本性由本性空。言自相空者，謂一切法自相，如質礙是色自相、領納是受自相、取像是想自相、造作是行自相、了別是識自相。如是等若有為法自相、若無為法自相，此自相空。言一切法空者，謂五蘊、十二處、十八界，若有色無色、有見無見、有對無對、有漏無漏、有為無為法，此一切法由一切法空。從此第六明因果空。

The commentary states: "Emptiness of dispersal" means that releasing, abandoning, and relinquishing can be apprehended; this dispersal is empty through dispersal. That sūtra next states "emptiness of non-alteration," meaning that no releasing, abandoning, or relinquishing can be apprehended; this non-alteration is empty through non-alteration. The former is being and the latter is non-being, mutually correlated in their characteristics. Although it is missing here, its meaning is implicitly correlated. As for "emptiness of intrinsic nature," it refers to the intrinsic nature of all phenomena: whether the nature of conditioned phenomena or the nature of unconditioned phenomena, none are made by śrāvakas, pratyekabuddhas, bodhisattvas, or tathāgatas, nor are they made by anything else; this intrinsic nature is empty through intrinsic nature. As for "emptiness of specific characteristics," it refers to the specific characteristics of all phenomena: such as resistance being the specific characteristic of form, experiencing being the specific characteristic of feeling, grasping marks being the specific characteristic of perception, constructing being the specific characteristic of karmic formations, and discerning being the specific characteristic of consciousness. Specific characteristics like these, whether of conditioned phenomena or unconditioned phenomena, are empty of specific characteristics. As for "emptiness of all phenomena," it refers to the five aggregates, twelve sense fields, and eighteen realms, whether phenomena with form or formless, visible or invisible, resistant or non-resistant, with outflows or outflowless, conditioned or unconditioned; all these phenomena are empty through all phenomena. Next is the sixth [part], clarifying the emptiness of cause and fruition.
