大方廣佛華嚴經隨疏演義鈔 79.10

79.10

疏「若離於緣性叵說故」者，即第四是相即門，亦是通妨。謂有問言：緣起約事、性起約理、如何相即？故為此通。從緣無性，方顯性起。又由見緣，推知性起，若離於緣，復論何性？離緣有性是斷空故。疏「下加性起」者，即第五段，引當經證，即以人表法門。

Regarding the Commentary's "If separated from conditions, nature cannot be spoken of": this fourth is the portal of identity, and also resolves an objection. That is, someone asks: conditioned arising concerns phenomena, while nature-arising concerns principle; how can they be identical? Therefore, this resolution is made: from conditions having no own-nature, nature-arising is only then revealed. Furthermore, by observing conditions, one deduces and knows nature-arising; if separated from conditions, what nature could one further discuss? Having nature apart from conditions is annihilated emptiness. In the Commentary, "Below, adding nature-arising..." is the fifth passage, citing this sūtra as proof, which is the portal of using persons to represent the Dharma.
