妙法蓮華經玄義 2.119

2.119

不思議不生不滅十二因緣者，為利根人即事顯理也。《大經》云：「十二因緣名為佛性」者，無明、愛、取既是煩惱，煩惱道即是菩提。菩提通達無復煩惱，煩惱既無，即究竟淨，了因佛性也。行、有是業道，即是解脫，解脫自在，緣因佛性也。名色、老死是苦道，苦即法身。法身無苦、無樂，是名大樂。不生不死是常，正因佛性。故言無明與愛，是二中間，即是中道。無明是過去，愛是現在，若邊若中無非佛性、並是常樂我淨，無明不生亦復不滅。是名不思議不生不滅十二因緣也。

Regarding the inconceivable non-arising and non-ceasing of the twelve links of conditioned arising: this manifests the principle directly through phenomena for those of sharp capacity. The Great Sūtra states: "The twelve links of conditioned arising are called buddha-nature." Since ignorance, craving, and grasping are afflictions, the path of afflictions is itself bodhi. Bodhi is thoroughly penetrating and has no further afflictions; since afflictions are absent, this is ultimate purity, the revealing-cause buddha-nature. Activity and existence are the path of karma, which is itself liberation; liberation is sovereign mastery, the conditional-cause buddha-nature. Name-and-form and aging-and-death are the path of suffering; suffering is itself the dharma-kāya. The dharma-kāya has neither suffering nor pleasure, and this is called great bliss. Non-arising and non-dying are permanence, the direct-cause buddha-nature. Therefore it is said that between the two—ignorance and craving—is the Middle Way. Ignorance is the past, and craving is the present; whether extreme or middle, there is nothing that is not buddha-nature, and all are permanence, bliss, self, and purity. Ignorance does not arise, nor does it cease. This is called the twelve links of the inconceivable non-arising and non-ceasing of conditioned arising.
