3.39

八、自性無記業者，基師解云：謂善不善非業道攝，中下品性，非三性中無記性也。自體不增名無記故，或三性中無記之業。

Regarding the eighth, ‘karma intrinsically indeterminate’ (自性無記業): Master Ji explains: ‘It refers to good and evil that are not subsumed under the paths of karma, of middling or inferior nature; it is not the indeterminate nature among the three natures. It is called indeterminate because its own entity does not increase; or it refers to indeterminate karma among the three natures.’
