次見、愛而辨三毒者，此二科既有合離之異，事須分別。若合但取癡一分為見，餘一分及貪、恚並合為愛也。若離則見愛之中各有三毒，如此歷三界五行，則離出九十八使。一切煩惱通名毒者，毒以沈毒為義，惱壞之甚，故云沈毒，以其能壞出世善心，故名為毒也。

The reason why the three poisons are distinguished next after views and craving is that since these two categories have the difference of being combined or separated, they must be differentiated. If combined, one merely takes one portion of delusion as views, and the remaining portion along with greed and anger are combined into craving. If separated, then within views and craving there are each the three poisons; tracking them in this way through the three realms and the five stages of practice, they separate out into ninety-eight anuśayas. The reason why all afflictions are collectively called 'poisons' is that 'poison' has the meaning of sinking poison, which vexes and destroys severely; hence it is called 'sinking poison.' Because they can destroy the wholesome mind that transcends the world, they are called poisons.
