瑜伽論記 12.145

12.145

Regarding "having thoroughly investigated all dharmas": The Tripiṭaka Master says: Prior to the seventh stage, both investigation and real knowledge exist. Now it says "having thoroughly investigated" because, by the power of the investigation of the previous seventh stage, real knowledge arises on the eighth stage and above; it is not that the eighth stage has investigation. Why is this so? Because on the eighth stage and above, one constantly enters the contemplation of the two emptinesses of person and dharmas at all times. Another explanation says: There is also an emergence from contemplation which is not an application-of-effort dharma, hence one does not cultivate the contemplation of investigation.
