法華經義記 1.53

1.53

又「阿若憍陳如」者，阿之言無，若之言智，詺為無智。憍陳如是外國姓，此方無翻。所以爾者，佛未出時此人是外道，唯計有為病，如來出世知其根熟，為說無生空理，後得羅漢。明此人從無生空理生智，故言無智憍陳如也。

Furthermore, regarding "Ājñāta-Kauṇḍinya": 'ā' means 'non-', 'jñāta' means 'wisdom'; he is called 'non-wisdom'. Kauṇḍinya is a foreign clan name, which has no translation in this land. The reason for this is that before the Buddha appeared in the world, this person was a non-Buddhist, only conceiving of the malady of the conditioned. When the Tathāgata appeared in the world, knowing that his faculties were mature, he expounded for him the empty principle of non-arising, and he later attained arhatship. This explains that this person generated wisdom from the empty principle of non-arising, hence he is called 'Non-wisdom Kauṇḍinya'.
