金光明經文句記 4.294

4.294

初、逆推過因。從名色起者，五果之初故、五陰已具故。識支未具五陰，故不言也。過去之因極於無明，今觀無明，意欲令觀成覺了智。而謂無明定是有等，則能破智翻為無明，藥乃成病，故云四句取者皆是無明，無明為緣，豈不生行生識等耶？如前說者，六入至老死，皆如前文直示中明。

First, retrogressively investigating past causes. Arising from name-and-form is because it is the beginning of the five results and because the five aggregates are already complete. The link of consciousness has not yet completed the five aggregates, so it is not mentioned. The causes of the past culminate in ignorance. Now contemplating ignorance, the intention is to make the contemplation become the wisdom of full awakening. Yet if one says that ignorance is definitely existent and so forth, then the wisdom that can eradicate it turns instead into ignorance; the medicine turns into the illness. Therefore it says that those who grasp through the four propositions are all [in] ignorance; with ignorance as condition, how could it not produce volitional formations, produce consciousness, and so forth? As for "as explained before," from the six sense bases to old age and death, all are clarified as in the preceding text's direct explanation.
