大方廣佛華嚴經隨疏演義鈔 81.22

81.22

疏「初句無生之生」者，如無生，性無生也；佛出興之，生也。下句例知。後句一切義成，故為大用。上三句是體，第四句是用。故云「餘不頌者含在此中」者，不出體用故。

As for the commentary's: "The first line is the arising of non-arising": as in non-arising, its nature is unarisen; the Buddha's arising and appearing is its arising. The lines below are understood by analogy. The final line accomplishes all meanings, and therefore is the great function. The upper three lines are the essence, and the fourth line is the function. Therefore it says: "Those remaining that are not eulogized are contained within this," because they do not go beyond essence and function.
