20.68

無明不別立，以非能取故者，不立無明別為取者，能取諸有，故名為取。謂不了相，名為無明，非能取故，不立為取，但可與餘合說為取。此上四取依薩婆多宗說也。若依經部，四取謂以貪為體性，貪緣五欲境起，名為欲取；貪緣六十二見起，名為見取；貪緣戒禁起，名戒禁取；貪緣三界我語起，名我語取。故彼四取以貪為體。

"Ignorance is not established separately, because it is not capable of grasping" means that ignorance is not established separately as a grasping because it is by being capable of grasping existences that it is called "grasping." Ignorance refers to the characteristic of non-comprehension; because it is not capable of grasping, it is not established as a grasping, but can only be spoken of as grasping together with the rest. These four graspings above are explained according to the Sarvāstivāda school. If one relies on the Sautrāntikas, the four graspings take greed as their essential nature: greed arising with the objects of the five desires as its object is called grasping at sensual desire; greed arising with the sixty-two views as its object is called grasping at views; greed arising with rules and observances as its object is called grasping at rules and observances; and greed arising with the doctrines of self of the three realms as its object is called grasping at the doctrine of self. Therefore, for them the four graspings take greed as their substance.
