俱舍論疏 23.126

23.126

論「若諸諦中至行相別故」，有部出頓見現觀過。四諦行相各別不同，如何一念能頓觀耶？

The Śāstra states: "If among the truths... up to: because the aspects (ākāra) are distinct." The Sarvāstivāda points out the flaw of simultaneous direct realization of vision: the aspects of the four truths are each distinct and different; how could one simultaneously contemplate them in a single mental moment?
