大方廣佛華嚴經隨疏演義鈔 14.34

14.34

疏「而法界等言」下，第三彰加不思議之所以。揀異餘經，故兼引文證。

Regarding the Commentary's passage starting from "Yet the words 'dharmadhātu' and so forth": this is the third [point], manifesting the reason for adding "inconceivable." It distinguishes [this sūtra] from other sūtras, and therefore concurrently cites textual evidence.
