俱舍論疏 26.63

26.63

論「此不應理至道智」，有部破西方師釋。一以理破、二違本論破。諸染污心與眠相應故名聚心，染污故應名散心。此則一心有二心過，此違理也。若謂聚心是眠相應，是即唯是欲界有漏心，即違本論類智、道智二智知也。類智知上界，道智知無漏道故（已上第四對）。

On the Śāstra's statement: "This is not logical […] the knowledge of the path": the Sarvāstivādins refute the explanation of the Western masters. First, they refute it by reason; second, they refute it by contradiction with the fundamental treatise. All defiled minds, because they are associated with sleepiness, would be called collected minds; but because they are defiled, they should be called distracted minds. This incurs the fault that a single mind has two states of mind, which contradicts reason. If one maintains that a collected mind is that which is associated with sleepiness, it would therefore be solely a tainted mind of the desire realm, which directly contradicts the fundamental treatise['s statement] that it is known by the two knowledges—subsequent knowledge and the knowledge of the path. This is because subsequent knowledge knows the higher realms, and the knowledge of the path knows the untainted path. (The above is the fourth pair.)
