佛遺教經論疏節要 1.497

1.497

已當中夜，所以不過，表中道也。中道二種，如前說。今顯表離斷常之中，亦密表佛性中也。我有三種：一見、二慢、三名字。如來見慢已盡，隨順世間名字稱我。今當灰滅假身，則名字亦無，即是無餘涅槃真無我法也。

It was already the middle of the night; that it had not yet passed symbolizes the middle way. There are two kinds of middle way, as explained before. Here it explicitly symbolizes the middle that is free from annihilation and permanence, and also secretly symbolizes the middle of Buddha-nature. There are three kinds of 'I': first, view; second, conceit; third, nominal designation. The Tathāgata has already exhausted view and conceit, and accords with worldly nominal designations in calling himself 'I'. Now, when his provisional body is reduced to ashes, even the nominal designation will not exist; this is precisely the true non-self Dharma of nirupadhiśeṣa-nirvāṇa.
