22.105

前中，言軌範師者，秉法者。親教師者，和上也。若同法者，能開悟者，令憶念者，則是同學先有解者。言開許制止一切應作不應作者，是大師故，時時教授教誡故者，是後三師。言當知則是能說、傳說及隨說者，結前三師也。

"An ācārya (disciplinarian)" refers to the one who upholds the Dharma. "An upādhyāya (preceptor)" refers to the master (heshang). "Fellow practitioners who can enlighten and cause to recollect" refers to fellow students who have already gained understanding. The statement "Permitting and prohibiting all things to be done and not to be done" refers to the Great Master; "constantly instructing and admonishing" refers to the latter three teachers. The statement "Know that these are the ones who can speak, hand down the teaching, and speak in accordance" concludes the previous three teachers.
