化地部（梵語也第三百年中從一切有部出梵言磨[醠-央+太]奢婆迦亦名彌喜捨婆柯此云化地亦云教地或言正地人名也但此羅漢在俗為王國主化土境故名化地今入佛法如地又匡化之故以名也舊名彌沙塞者訛也）。

Mahīśāsaka (Sanskrit. In the third century [after the Buddha's parinirvāṇa], it branched off from the Sarvāstivāda. In Sanskrit, mahīśāsaka, also named miyishebake; here it is translated as 'transforming the earth', also as 'teaching the earth', or 'correct earth'—it is a person's name. When this arhat was still a layman, he was a king who transformed and governed his realm, hence was called 'transformer of the earth'; now that he has entered the Buddha's Dharma, he sustains and transforms it like the earth, hence the school was named after him. The old name Mishasai is corrupt).
