大般涅槃經義記 6.47

6.47

就八門中，初一知非，後七知是。前知非中，「若行緣」者，知邪法緣是不得出離解脫故曰行緣。

Among the eight headings, the first one knows what is wrong, and the latter seven know what is right. In the former knowing what is wrong, "if the conditions of practice": knowing that the conditions of deviant dharmas do not allow one to attain deliverance and liberation, hence called "conditions of practice."
