此以有宗等智為喻。三類智者，謂苦、集、滅三諦類智，起此類智現觀後已，而能兼修有漏知苦、斷集、證滅所有俗智，即此俗智因此三類智現觀後邊而修習故，故名現觀。故《俱舍論》二十六云：「唯苦、集、滅三類智時，能兼修未來現觀邊俗智，於一一諦現觀後邊，方能兼修，故立斯號。」

This takes the conventional cognition of the Sarvāstivāda school as an analogy. 'Cognitions of the three kinds' refers to the subsequent cognitions of the three truths of suffering, origination, and cessation. After giving rise to the direct realization of these subsequent cognitions, one can concurrently cultivate the defiled conventional cognitions that know suffering, abandon origination, and realize cessation. Since this conventional cognition is cultivated at the conclusion of the direct realization of these three subsequent cognitions, it is called 'at the edge of direct realization'. Therefore, the Abhidharmakośa, fascicle 26, states: 'Only at the time of the three subsequent cognitions of suffering, origination, and cessation can one concurrently cultivate the conventional cognition at the edge of future direct realization. Only at the conclusion of the direct realization of each single truth can one concurrently cultivate it; thus this name is established.'
