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.
