大方廣佛華嚴經隨疏演義鈔 14.10

14.10

疏「安知因緣性空」等者，第二況出深旨。因緣有相，淺義尚迷，性空真理安測涯分？性空通於初頓終教，妙有即是實教。若通於空有二文交徹，具德即是圓教。

Regarding the commentary's "how could they know that the nature of causes and conditions is empty" and what follows: this is the second [part], using comparison to bring out the profound purport. Since they are still deluded regarding the shallow meaning—the marks of existence of causes and conditions—how could they fathom the boundaries of the true principle of emptiness of nature? Emptiness of nature applies through the initial, sudden, and final teachings; wondrous existence is the actual teaching. If it applies to the interpenetration of both texts of emptiness and existence, possessing all virtues, that is the perfect teaching.
