憍陳那（亦梵語也是其姓也解則彰其美德姓則[厂@千]其氏族德姓合目曰以名之是佛最初得度聖弟子也）。

Kauṇḍinya (憍陳那: also Sanskrit; this is his clan name. 'Ājñāta' makes clear his noble virtue, while the clan name makes clear his lineage. Joining his virtue and clan name forms his designation. He was the very first holy disciple liberated by the Buddha).
