【彌勒】《西域記》云：「梅哩麗耶，唐云慈氏，即姓也。舊曰彌勒，訛也。」什曰：「姓也。阿逸多，字也。南天竺婆羅門子。」《淨名疏》云：「有言從姓立名，今謂非姓，恐是名也。何者？彌勒，此翻慈氏，過去為王，名曇摩流支，慈育國人，自爾至今，常名慈氏。姓阿逸多，此云無能勝。有言阿逸多是名，既不親見正文，未可定執。」《觀下生經》云：「時修梵摩，即與子立字，名曰彌勒。」

[Maitreya]: The Xiyu ji says: "Meililiye in Tang is rendered Cishi (Benevolent Clan); that is the clan name. The old form Mile was an error." Kumārajīva said: "It is a clan name. Ajita is the personal name. He was the son of a South Indian brāhmaṇa." The Commentary on the Vimalakīrti says: "Some say it is named after the clan, but we now consider it not to be a clan, but rather a personal name. Why? Maitreya is here translated as Cishi. In the past, he was a king named Dharmaruci who benevolently nurtured the people of his country; from then until now, he has always been named Cishi. His clan is Ajita, which is translated here as Invincible (Wunengsheng). Some say Ajita is a personal name, but not having personally seen an authentic text, one cannot hold to this definitively." The Guan xiasheng jing says: "At that time Brahmāyu gave his son a personal name, calling him Maitreya."
