若有妄取隨順此見乃至此戒禁是迷苦諦者，景云：身語二業是戒禁體，有從同類因等流果義名苦。今迷此苦執戒為勝。

As for 'If one falsely grasps what conforms to this view down to these precepts and vows, it is delusion regarding the truth of suffering': Jing says: The two karmas of body and speech are the essence of precepts and vows; possessing the meaning of a flow-out fruit from a cause of the same category, they are called suffering. Now, being deluded regarding this suffering, one grasps precepts as superior.
