8.18

不一下，釋非一，文四：今初、躡前正釋，四：初、正釋。攝末之本，即生滅之真如；攝本之末，即真如之生滅。既一生滅、一不生滅，豈為一義？是則於心不異中明不一義。

Under 'not one', explaining non-oneness, the text has four: now first, continuing from the preceding to directly explain, in four [parts]: first, directly explaining. The root that subsumes the branches is the tathatā of arising-and-ceasing; the branches that subsume the root are the arising-and-ceasing of tathatā. Since one is arising-and-ceasing and one is unarising-and-unceasing, how could they have the meaning of oneness? Thus within the non-difference of mind, it clarifies the meaning of non-oneness.
