四明尊者教行錄 4.69

4.69

答：三藏菩薩二三僧祇雖用煖頂觀法，正為伏惑，行諸事行；若到樹下，行為真故，復用四法為斷惑加行也。如三祇久伏三界思惑，而於樹下仍用三十四心。以此驗之，知非碩異。

Answer: Although the bodhisattva of the Tripiṭaka uses the contemplation methods of heat and summit during the second and third asaṃkhyeyas, it is specifically to subdue delusions while practicing various phenomenal deeds. When he reaches beneath the tree, because his practice is genuine, he again uses the four dharmas as preliminary application to sever delusions. Just as through the three asaṃkhyeyas he long subdues the delusions of thought of the triple world, yet under the tree he still employs the thirty-four mental moments. Verifying it by this, we know there is no great discrepancy.
