大般涅槃經義記 9.236

9.236

上來正辨乳酪有無，下約四緣生識顯之。於中先明四緣生識，後顯乳酪。前中，初言「四緣生識，眼、色、明、欲」舉其喻事。次就此事明非有無，「是眼識性非眼色」等明其非有，「從和合生」彰其非無。「如是眼識本無今有、已有還無，是故當知無有本性」，釋前非有，非無易知略而不解。

The preceding directly distinguishes the existence and non-existence of milk and curd; below it reveals it with reference to the four conditions producing consciousness. In this, it first clarifies the four conditions producing consciousness, and afterwards reveals milk and curd. In the former, it first states: "Four conditions produce consciousness: eye, form, light, and desire," adducing the subject matter of the analogy. Next, with reference to this matter, it clarifies neither-existence-nor-non-existence: "the nature of this eye-consciousness is not the eye, form," and so forth, clarifies that it is not existent; "arising from combination" indicates that it is not non-existent. "Such an eye-consciousness is originally non-existent and now existent, and having existed, becomes non-existent again; therefore one should know that it has no original nature" explains the preceding 'not existent'; 'not non-existent' is easy to know, so it is briefly omitted without explanation.
