華嚴經探玄記 1.80

1.80

二法名者，依《智度論》，〈屬累品〉云名不思議解脫經有十萬偈，又彼中自指是《華嚴》故，良為此經所說之法皆一攝一切，無不悉是不思議解脫，故以為名。

Second, the dharma name: according to the Dà zhìdù lùn, the "Entrustment Chapter" states that the sūtra named Inconceivable Deliverance has one hundred thousand verses, and furthermore that text itself points out that this is the Avataṃsaka. This is truly because the dharmas taught in this sūtra all take one to encompass all, and none are anything other than inconceivable deliverance; hence it is named for this.
