大方廣佛華嚴經隨疏演義鈔 76.17

76.17

疏「謂無有亦無故」者，經有二句，云非有非無有。今偏釋非無有句，謂非有即是無有。今亦遣彼無有，故云非有非無有，故云無有亦無。上句易故不釋。叡公云：「眾生如化，非有非真。不達此者，轉如車輪。解法清淨，無我無人，眾垢消除，如日無雲。」

Regarding the commentary's "Meaning that non-existence is also non-existent": the sūtra has two lines, saying "neither existent nor non-existent." Here it specifically explains the line "not non-existent": "not existent" means non-existent, and now it also dispels that non-existence, hence it says "neither existent nor non-existent," which means non-existence is also non-existent. The preceding line is easy, so it is not explained. Master Rui says: "Sentient beings are like an illusion, / neither existent nor real. / Those who do not comprehend this / revolve like a chariot wheel. / Understand that dharmas are pure, / without self and without person; / when the multitude of defilements is extinguished, / it is like the sun without clouds."
