大方廣佛華嚴經隨疏演義鈔 6.2

6.2

疏「今承理教之力略啟四門」下，第三開章別釋也。於中先標、後釋。今初也。應有難云：既極位方知，何以凡情輒窺大教？故此云耳，依憑教理，聖教許故。故《涅槃》云「具縛凡夫能知如來祕密之藏。」〈毘盧遮那品〉云「如因日光照，還見於日輪。我以佛智光，見佛所行道。」即因佛教能了教也。即仰推之智，信解而知耳。

Regarding the commentary's passage beginning "Now, relying upon the power of principle and teaching, I briefly open four gates": This is the third part, opening chapters for specific explanation. Within this, it first posits and then explains. Now, this is the first. There might be an objection: Since only at the ultimate stage can it be known, how can ordinary sentiments dare to peer into the great teaching? Therefore this is said: relying upon the teaching and the principle, for the sacred teachings permit it. Thus the Nirvāṇa Sūtra states: "An ordinary being fully bound by defilements is capable of knowing the secret treasury of the Tathāgata." The "Chapter on Vairocana" states: "Just as by relying on the illumination of the sunlight / one turns back to see the solar disk, / so I, by the light of the Buddha's wisdom, / see the path traversed by the Buddha." That is, by relying on the Buddha's teaching, one is capable of understanding the teaching. It is simply the wisdom of reverent inference, known through faith and understanding.
