成唯識論了義燈 3.52

3.52

頌分或為十一門，以不可知，唯此識有，餘識所無，故別為門。別離受俱，故有十一。或受攝入心所門中，即為十門。若不可知，即二行相，不別為門。即離說受故，但十門。

The verse may be divided into eleven topics: because "unfathomable" is possessed only by this consciousness and is absent in the other consciousnesses, it forms a distinct topic. Separating feeling as concurrent gives eleven. Or, feeling may be subsumed into the topic of mental factors, which results in ten topics. If "unfathomable" is regarded as the two aspects, it does not form a distinct topic; and since feeling is spoken of separately, there are still only ten topics.
