金光明經文句記 4.276

4.276

二、引證。無明轉即變為明，名菩提燈。若非感應因緣之力，豈滅無明？故知成佛全假因緣。

Second, citing proof: when ignorance is transformed, it becomes illumination, termed the lamp of bodhi. Were it not for the power of causes and conditions of resonance and response, how could ignorance be extinguished? Therefore, one knows that attaining Buddhahood entirely relies on causes and conditions.
