妙法蓮華經玄義 2.115

2.115

二、思議不生不滅十二者，此以巧破拙。《中論》云：「為利根弟子說十二不生不滅。」癡如虛空，乃至老死如虛空：無明如幻化，不可得故，乃至老死如幻化，不可得。《金光明》云：「無明體相，本自不有，妄想因緣，和合而有。」不善思惟心行所造，如幻師在四衢道，幻作種種象、馬、纓珞、人物等，癡謂真實、智知非真。無明幻出六道依正，當知本自不有，無明所為。如知藤本非蛇，則怖心不生，不生故不滅。是名思議不生不滅十二因緣相也。

Second, the conceivable twelve [causes and conditions] of non-arising and non-cessation: this uses the skillful to break the crude. The Madhyamaka-śāstra says: 'For disciples of sharp faculties, he speaks of the twelvefold non-arising and non-cessation.' Folly is like space, up to aging and death being like space; because ignorance is like an illusion and ungraspable, up to aging and death being like an illusion and ungraspable. The Suvarṇaprabhāsa says: 'The substance and characteristics of ignorance inherently do not exist; they exist as a combination through the conditions of false discrimination.' Produced by improper reflection and mental action, it is like an illusionist at a crossroads conjuring various elephants, horses, necklaces, people, and objects: the foolish consider them real, while the wise know they are not real. Ignorance conjures up the circumstantial and direct rewards of the six destinies; one should know that inherently they do not exist, being caused by ignorance. Just as when one knows a rope is originally not a snake, a fearful mind does not arise; not arising, it therefore does not cease. This is named the characteristic of the conceivable twelvefold causes and conditions of non-arising and non-cessation.
