大般涅槃經義記 3.245

3.245

就下辯實異相之中，約就愚智顯法是非。義要有二：一約愚辯非、二約智明是。文有三對：一明愚智迷悟得失、二彰其損益、三雙結非是。就初對中，先迷、後悟。迷中有二：一正明其迷、二明迷有失。迷中，「若人不知如來甚深境界」，迷如來藏佛性境界；「不知如來微密法身」，謂是食身，非是法身，迷佛法身；「不知如來道德威力」，迷佛報身。亦可前句迷於佛心，後迷佛德。

In differentiating below that the real differs from marks, it reveals the right and wrong of the Dharma with respect to the foolish and the wise. The essential meaning has two aspects: first, treating the foolish to differentiate the wrong; second, treating the wise to clarify the right. The text has three pairs: first, clarifying the delusion, awakening, loss, and gain of the foolish and the wise; second, demonstrating their detriment and benefit; third, concluding both the wrong and the right. In the first pair, there is first delusion and afterward awakening. Under delusion there are two: first, directly clarifying their delusion; second, clarifying that delusion has loss. Under delusion, "if a person does not know the Tathāgata's profound realm" means being deluded about the realm of the tathāgatagarbha and buddha-nature; "does not know the Tathāgata's subtle and secret dharmakāya" means considering it an alimentary body and not the dharmakāya, being deluded about the Buddha's dharmakāya; "does not know the Tathāgata's virtue and mighty power" means being deluded about the Buddha's saṃbhogakāya. It can also be that the former phrase is delusion regarding the Buddha's mind, and the latter is delusion regarding the Buddha's virtues.
