大般涅槃經集解 67.18

67.18

Sengliang comments: These four factors come together, yet three are of the nature of form (rūpa), and only consciousness is not of the nature of form. Since cause and effect differ in nature, this proves non-existence. Sengzong says: He again provides an explicit metaphor to clarify non-existence within the cause. Just as the coming together of the four factors produces consciousness: if you search for consciousness within empty space and light, how could it be found? Zhixiu says: Fourth, he directly explains the principle of a cause producing an effect.
