維摩經義疏 1.28

1.28

又阿難從佛聞法，莫生三慧，則自在稱我。問：佛法無我，何得稱我？答：說我有三。一邪見心說，如凡夫外道；二慢心說，如諸學人；三名字說，如諸羅漢。阿難了知實相非我非無我，隨世俗故稱之為我，即無我而我。不聞而聞稱為我聞。

Furthermore, when Ānanda heard the Dharma from the Buddha, not one of the three kinds of wisdom failed to arise; thus he sovereignly said "I". Question: The Buddha's Dharma is without a self; how can he say "I"? Answer: Speaking of "I" has three kinds: first, speaking with a mind of wrong views, like ordinary beings and non-Buddhists; second, speaking with a mind of conceit, like practitioners still in training; third, speaking in terms of mere designation, like the arhats. Ānanda thoroughly understood that the true mark is neither self nor non-self, and following worldly convention he therefore called it "I"; that is, a self that is non-self. Hearing without hearing is called "have I heard".
