瑜伽論記 3.91

3.91

生不定中，軌範師等者，基云：阿遮利耶名軌範師，鄔波拕耶名親教師，則和尚阿闍梨。廣博脇山者，舊云毘富羅山，其形如非天脇也。

In 'uncertainty of birth,' regarding 'disciplinarian' and so on, Ji says: an ācārya is called a disciplinarian (guifanshi), and an upādhyāya is called a preceptor (qinjiaoshi); that is, the upādhyāya and the ācārya. The 'Vipula flank mountain' was formerly called Vipula mountain; its shape is like the flank of an asura.
