答：前明起作分唯觀十支，此明寂滅分通觀十一支，欲滅生死煩惱業報故，其中無明行最是生死本故，寂滅分中通觀十二支也。又起作分中逆觀十二支，寂滅分中順觀十二支，由無明滅故行滅乃至生滅故老死滅，故云順逆觀也。此中有二：初、約有漏正見以明四諦觀，二、又以正見已下，約無漏正見以明四諦觀，為此義故已下，凡釋經中句義也。

Answer: The former clarifies the active phase, merely observing ten factors; this clarifies the phase of cessation, comprehensively observing eleven factors. Because one wishes to extinguish the afflictions, karma, and retributions of cyclic existence, and among them ignorance and formative forces are the primary root of cyclic existence, within the phase of cessation all twelve factors are comprehensively observed. Furthermore, within the active phase, one contemplates the twelve factors in reverse; within the phase of cessation, one contemplates the twelve factors in direct progression: due to the cessation of ignorance, formative forces cease, and so forth, up to the cessation of birth causing old age and death to cease; hence it is called "direct and reverse contemplation." Herein there are two aspects: first, explaining the contemplation of the four truths according to tainted right view; second, "furthermore, through right view..." below explains the contemplation of the four truths according to taintless right view. "For this reason..." below generally explains the meanings of the phrases in the sūtra.
