詳曰：觀後問意，其非福行既無明俱，即是無明。無明為緣，答意可悉。今助一解，前聚心品望後聚品總為無間，無明望行為無間緣，不約別對後無明說，由斯但說無明望行為無間緣，故無有失。

Detailed analysis: Examining the intent of the subsequent question, since non-meritorious formations coexist with ignorance, they are precisely ignorance. The answer's intention regarding ignorance acting as a condition can be understood. Now I provide an additional explanation: the preceding mental aggregate as a whole acts as an immediate condition for the succeeding mental aggregate; ignorance acting as an immediate condition for conditioned formations is not stated in terms of an individual correspondence with a succeeding ignorance; therefore, merely saying that ignorance acts as an immediate condition for conditioned formations incurs no fault.
