成唯識論述記 2.608

2.608

述曰：依前依他執為實有，不稱似法，故體定無，此即以理成內相有唯心所現，以外境無。下以經證。

The Commentary states: Clinging to them as really existent based on the aforementioned dependent [nature], they do not match the semblance of phenomena; therefore, their substance is definitively non-existent. This establishes by reason that the internal nimitta exists as manifestation of mind alone, and that external objects are non-existent. Below, scriptural proof is adduced.
