唯識二十論述記 1.237

1.237

The commentary says: This is the second verse, which explains the intentional meaning. The older translation says: 'Therefore the Buddha spoke of these two,' calling the internal and external bases 'two'. They resemble material bases, so he says 'to be ten'; they are not in contradiction. That is to say, when the six internal consciousnesses arise as actual states from their own seeds, these actual consciousnesses transform and operate resembling the appearances of objects such as form, not that the ten bases such as form exist externally as substantially real entities. In order to shatter the real self and establish the internal and external bases, the World-Honoured One taught that the ten bases such as form exist—this is the meaning here.
