大方廣佛華嚴經隨疏演義鈔 6.42

6.42

疏「亦立三教」下，顯立義也。於中漸約不具、頓約具說，不同遠公大小相望成漸頓也。言「具說」者，即如《涅槃》說「空者所謂生死，不空者所謂大涅槃」等。又云「若空不空、若常無常」等，皆令廣聞，即時頓也。三圓教者，即是華嚴。

Regarding the commentary's "also established three teachings" and below: this reveals the doctrine he established. Within this, "gradual" is explained in terms of incompleteness, and "sudden" is explained in terms of completeness; this differs from Master Yuan's establishing gradual and sudden in mutual contrast between the Hinayāna and Mahāyāna. "Completeness" refers to statements such as in the Nirvāṇa [Sūtra]: "The empty refers to saṃsāra, and the non-empty refers to great nirvāṇa," and so on; and further: "whether empty or non-empty, whether permanent or impermanent," and so on, all causing them to hear extensively—this is the sudden. The third, the round teaching, is precisely the Avataṃsaka.
