法華經義記 1.61

1.61

「阿㝹樓馱」者，亦是外國音，此間翻者，阿之言無，[菟-?+?]樓馱言貧，謂無貧比丘。此羅漢乃非多積財寶，但凡所至處衣服飲食觸事勝人。此人昔日五百世中，廣行布施給救貧窮，今餘報未盡稱無貧。

"Anuruddha" is also a foreign phonetic rendering. Translated here: "a-" means non-, and "-ruddha" means poor, signifying the "non-poor monk". It was not that this arhat accumulated much wealth and treasure, but merely that wherever he went, his clothing, food, and drink, and all matters he engaged with, surpassed those of other people. In the past, across five hundred lifetimes, this person widely practiced giving to relieve the impoverished; now, because the residual retribution has not yet run out, he is called "non-poor".
