成唯識論演祕 4.457

4.457

與別境念行相相似。念前說無，忘念同念，故不說也。有義：若爾，不正知亦爾，何須解之？故此但是論主遺忘。

Its ākāra is similar to the mindfulness of the particular states. Mindfulness was previously said to be absent; forgetfulness is identical to mindfulness, so it is not spoken of. One opinion holds: If so, incorrect knowing is also like this; why must it be explained? Therefore this is merely an oversight by the author of the treatise.
