首楞嚴義疏注經 1.66

1.66

具云摩訶沒特伽羅，此云大采菽氏，又云胡豆，即尊者母姓。上古仙人所嗜，因以命族。左面弟子，神通無過。下經云「我遊十方得無罣礙」，神通發明推為無上。

Fully called Mahāmaudgalyāyana, translated here as "Great Bean-Gatherer Clan," and also called "Chickpea," which was the venerable one's mother's surname. In high antiquity, ṛṣis relished this, and it was thereby used to name the clan. He was the disciple at the Buddha's left side, unsurpassed in supernatural powers. Later in the sūtra it says: "I roamed the ten directions attaining freedom from obstruction"; in the illumination of supernatural powers he is exalted as unexcelled.
