77.27

疏「三顯不思議」，中三：初泛舉法體、二「就後一中」下別語此經、三「前並是宗」下結歸宗趣。二中四者：「一何者不思議」，徵不思議法體。答謂智悲等。「二於何不思議」，徵不思議人。答謂世間等此人不能思議。「三云何不思議」，徵不思議體。謂聞思等思不及故。「四何用不思議」，徵不思議意，謂如來說法本欲利生，今絕言思於物何益？答意云：令信入故。謂欲證入，要須心絕動搖、言忘戲論耳。

Regarding the commentary's "Third, revealing the inconceivable": within it are three: first, generally adducing the essence of the dharma; second, from "Within the latter one" downward, specifically speaking of this sūtra; third, from "The foregoing are all the tenets" downward, concluding into the doctrinal purport.

Within the second, there are four:
1. "What is the inconceivable?"—inquiring into the essence of the inconceivable dharma. The answer states: cognition, compassion, and so forth.
2. "To whom is it inconceivable?"—inquiring into the person for whom it is inconceivable. The answer states: the worldly and so forth; such persons cannot conceive it.
3. "How is it inconceivable?"—inquiring into the essence of the inconceivability. Meaning that it is beyond the reach of thinking through hearing, contemplating, and so forth.
4. "For what purpose is it inconceivable?"—inquiring into the intention of the inconceivability. Meaning: when the Tathāgata expounds the Dharma, it originally aims to benefit sentient beings; now being beyond speech and thought, what benefit is it to beings? The meaning of the answer states: to enable them to enter through faith. Meaning that if one wishes to realize and enter, the mind must necessarily cease agitation and words must forget prapañca.
