[181] How does one define the unincluded (apariyāpanna) dhammas as wholesome (kusala) and define them as indeterminate (abyākata)? One defines the four noble paths as wholesome; one defines the four fruits of the monkhood (sāmaññaphala) and Nibbāna as indeterminate. Thus one defines the unincluded dhammas as wholesome and defines them as indeterminate. Thus one defines dhammas.
