成唯識論演祕 2.402

2.402

釋曰：一切有情而等有故名無差別，差別有情同類等有，名有差別。准法同分亦合有二，但論略也。且如五蘊，蘊義是同，此相似因名無差別，蘊蘊各別自相似因，名有差別，界、處等法皆倣於此。

The explanation says: Because it is possessed equally by all sentient beings, it is called 'without distinction'; because it is possessed equally by a similar class of differentiated sentient beings, it is called 'with distinction.' By analogy, the generic similarity of dharmas should also have two, but the treatise is concise. For instance, in the case of the five aggregates, the meaning of 'aggregate' is identical; this cause of resemblance is called 'without distinction.' The individual, specific cause of resemblance of each aggregate is called 'with distinction.' Dharmas such as the dhātus and āyatanas are all modeled on this.
