大般涅槃經義記 9.238

9.238

「是故我」下是第三段舉說證成。是前乳酪同彼四緣所生眼識，本無今有、已有還無，「故我說言因生法有、因滅法無」。

From "Therefore I" below is the third section, adducing teachings to corroborate and establish [it]. These preceding milk and curd are like that eye-consciousness produced by the four conditions, originally non-existent and now existent, and having existed, becoming non-existent again: "Therefore I say that dharmas produced by causes exist, and dharmas ceased by causes do not exist."
