大方廣佛華嚴經隨疏演義鈔 17.67

17.67

疏「若約法性」下，第三約法性宗辯，而但明圓教中意。言「以我無我不二之真我」者，含兩經意：一者《淨名》云「於我無我而不二，是無我義。」二者《涅槃》云「無我法中有真我，是故敬禮無上尊。」正當今意，即口順世間，心造真境，真自在我。

In the commentary, from “If based on dharmatā” downward is the third [section], explaining according to the Dharmatā School, which clarifies only the intent of the perfect teaching. The statement “with the true self of the non-duality of self and non-self” encompasses the intent of two sūtras: first, the Vimalakīrtinirdeśa says, “That there is no duality between self and non-self is the meaning of non-self”; second, the Nirvāṇa Sūtra says, “Within dharmas of non-self there is the true self; therefore I pay homage to the Unsurpassed Honoured One.” This directly fits the present intent: with the mouth according with the world and the mind reaching the true realm, this is the true self of sovereign ease.
