成唯識論演祕 4.349

4.349

釋：無餘自類心來隔也。即餘自類，類雖是同，而非即此，亦名異也。若言異識名餘異者，住無心位有七、八間，云何得言入、出二心無間耶？故如前釋。

Explanation: No other mind of its own class comes to intervene. That other of its own class, though of the same class, is not this very one, and thus is also termed 'different'. If one were to say that 'other and different' means a different consciousness, then during the mindless state there are the seventh and eighth intervening; how could one say that the two minds entering and emerging are immediate? Therefore, it is as explained before.
