成唯識論演祕 6.209

6.209

有何所以意執斷耶？執既不斷與五同緣，故知五俱第六意識有執無妨。

What reason would there be for the mental grasping to be severed? Since grasping is not severed and takes the same ālambana together with the five [consciousnesses], we know that there is no problem in grasping existing in the sixth mental consciousness concurrent with the five.
