Note 12 — Chapter XXXI · GAYÂ. ŚÂKYAMUNI’S ATTAINING TO THE BUDDHASHIP; AND OTHER LEGENDS.
James Legge translation
These must not be confounded with Mahâkaśyapa of chap. xvi, note 17. They were three brothers, Uruvilvâ, Gayâ, and Nadî-Kâśyapa, up to this time holders of ‘erroneous’ views, having 500, 300, and 200 disciples respectively. They became distinguished followers of Śâkyamuni; and are—each of them—to become Buddha by-and-by. See the Nidâna Kathâ, pp. 114, 115.
