分別功德論 2.8

2.8

As for the "venerable disciples", it means that among the five hundred arhats each had their specialty: some were foremost in wisdom, some in ṛddhi, some in eloquence, some in merit, some in keeping the precepts, some in contentment, or some in preaching the Dharma—each held the foremost position. If one wishes to discuss the elder brother coming before the younger brother, Ājñātakauṇḍinya was the eldest and Subhadra was the youngest; this is the broad outline of the hierarchical order in the Buddha's Dharma. If one were to take cleverness, intelligence, and broad erudition as the head, that would merely be the way of the brāhmaṇas.
