「目連」者，姓大目連也。是其母姓，此云讚誦，亦云萊茯根，字俱律陀，父母無兒禱俱律陀樹神因生是子，故以樹為名也。真諦三藏云：「應言勿伽羅，勿伽者此言胡豆，即綠色豆，羅此云受，合而為言應言受胡豆，蓋是其姓。上古有仙人名勿伽羅，不食一切物唯食此豆，故名受胡豆，其是仙人種故以為名」也。

Regarding "Maudgalyāyana": his clan is Mahāmaudgalyāyana. This was his mother's clan, translated here as "praising and reciting," and also as "radish root." His personal name was Kolita. His parents had no children, and praying to the spirit of a kolita tree, this son was born as a result, so he was named after the tree. Tripiṭaka Master Paramārtha said: "It should be said as *Maudgala*. *Maudga* is translated here as mung bean, which is a green bean; *la* is translated here as 'receiving.' Compounded together, it should be called 'receiving mung beans,' which is indeed his clan. In ancient times there was a sage named Maudgala who did not eat anything at all except this bean, and thus was named 'Receiving Mung Beans.' He is of this sage's lineage, and thus it was taken as his name."
