摩訶止觀 3.162

3.162

若別圓二人，通惑先盡，別惑被伏，生彼界者神根即利；但修中觀，治彼三道。從於初地乃至後地，地地中皆有三道。地地無明分分滅，業滅、苦滅。地地相應去時，獨頭亦去。地地雖有智，智與無明雜；雜故，亦得呼為智障，障上分智故。唯佛心中無無明，則煩惱道盡；煩惱道盡，故業盡；業盡，故苦盡。三道究竟，唯在如來。是故中觀攝得界外惑也。

If it is the two persons of the distinctive and perfect [teachings], whose shared delusions were exhausted first and whose distinctive delusions have been subdued, upon being born in that realm their spiritual faculties are keen; they only practice the contemplation of the middle way, remedying those three paths. From the first ground up to the later grounds, in every ground there are the three paths. Ground by ground, avidyā is extinguished part by part, karma is extinguished, and suffering is extinguished. When that which is associated is eliminated ground by ground, that which is isolated is eliminated as well. Although in ground after ground there is wisdom, wisdom is mixed with avidyā; because it is mixed, it may also be termed the hindrance of wisdom, because it hinders higher-level wisdom. Only in the mind of the Buddha is there no avidyā, and so the path of afflictions is exhausted; because the path of afflictions is exhausted, karma is exhausted; because karma is exhausted, suffering is exhausted. The ultimate culmination of the three paths resides solely in the Tathāgata. Therefore, the contemplation of the middle way encompasses delusions beyond the realms.
