首楞嚴義疏注經 10.108

10.108

問：前三陰盡，唯行識二陰，何得更執前三又不言識？答：前之三陰觀中雖破，但約觀法增勝不被陰迷，善巧安忍不生過患，豈可都無謂之破耶！今觀行陰，依止前三遷流相續，故執三也。不言識者，行陰覆故，由是通前而不言識也。

Question: The first three aggregates have ended, leaving only the two aggregates of formations and consciousness; how can he further cling to the first three and not speak of consciousness? Answer: Although the preceding three aggregates were broken through within contemplation, this is only in terms of the superior strength of the contemplative method, not being deluded by the aggregates, skillfully enduring without generating faults; how could it be said that their total absence constitutes breaking through! Now, contemplating the aggregate of formations, it relies on the flux and continuity of the preceding three, hence he clings to the three. As for not speaking of consciousness, it is because it is covered by the aggregate of formations; therefore it runs through the preceding ones without mentioning consciousness.
