大般涅槃經義記 3.230

3.230

第三段中先明佛性非有非無，「若有說」下明其無犯。前中初言「有諸外道或說斷常」舉邪顯正，「如來不」下辯正異邪，不犯可知。

In the third section, it first clarifies that the buddha-nature is neither existent nor non-existent; from "If someone speaks" below, it clarifies that there is no infraction. In the former part, it first says, "There are non-Buddhists who speak either of annihilation or permanence," raising the deviant to reveal the correct. From "The Tathāgata does not" below, it distinguishes the correct from the deviant; that there is no infraction can be understood.
