成唯識論演祕 4.370

4.370

有義：即心自體說名見分，非四分中第二見分，世親同時唯二分故。

There is an opinion: It is the intrinsic nature of the mind itself that is spoken of as the subjective aspect (darśana-bhāga), not the second subjective aspect among the four aspects, because at the time of Vasubandhu there were only two aspects.
