俱舍論疏 20.83

20.83

論「若如現有至其理自成」，經部進退責有部也。若謂去、來如現有，應成現世。若體現無，不同現在，則應許有緣無境識，其理自成。

The Śāstra says: "If they exist like the present... the principle is naturally established": the Sautrāntikas press the Sarvāstivādins from both sides. If they claim that the past and future exist like the present, they would become the present time. If their substance is presently non-existent, unlike the present, then they must admit that there is a consciousness that takes a non-existent object, and the principle is naturally established.
