大般涅槃經義記 3.116

3.116

第三，不從有損喻中，損事顯彰名「作是言」，始行之流守正不從名「無一人為我師者」，敗正同邪故言「要令」，諸婆羅門「與栴陀羅共住止」等，共住止宿明其身同，同其事業明其行同。

Third, in the metaphor of there being detriment in not following: the matter of detriment being made manifest is called 'making this statement.' The class of initial practitioners preserving the correct and not following is called 'there is not one person who will be my master.' Ruining the correct to conform to the heterodox is why it says 'must cause' all the brāhmaṇas 'to dwell and reside together with the caṇḍāla' and so forth. Dwelling and staying together explains that their bodies are the same; sharing in his enterprises explains that their practice is the same.
