大般涅槃經義記 7.406

7.406

「如見畫」下第二復次，「非緣生染」證貪是有，「見畫生貪」正明貪有。畫女非是可貪境界而見生貪，明知心中先有貪性，「以生貪故得種種罪」舉罪顯有。「若本無」下破無成有，破相可知。

From "Just as seeing a painting" onward is the second point: "defilement arising from what is not a condition" proves that greed exists; "seeing a painting gives rise to greed" directly clarifies that greed exists. A painted woman is not an object that can be craved, yet seeing it gives rise to greed; one clearly knows that the nature of greed previously existed in the mind. "Because greed is generated, one incurs various sins" cites sins to reveal existence. From "If it were fundamentally nonexistent" onward refutes nonexistence to establish existence; the manner of refutation can be understood.
