大般涅槃經義記 8.246

8.246

前教見佛、次教見性，自下第三雙顯前二。師子先問「如佛所說見於如來及見佛性，是義云何」，問其見相。「如來之身無相貌」下，難其可見。於中，先明佛身離相不可得見，後類佛性。

Previously, it taught seeing the Buddha; next, it taught seeing the nature; from here below is the third [part], revealing both of the former two together. Siṃhanāda first asks: 'As the Buddha has spoken of seeing the Tathāgata and seeing the buddha-nature, what is the meaning of this?', asking about the characteristics of seeing them. From 'The body of the Tathāgata has no physical marks...' below, he challenges the possibility of seeing them. Therein, he first explains that the Buddha's body is free of marks and cannot be seen, and afterward analogizes the buddha-nature to it.
