[180] How does one define (vavattheti) dhammas belonging to the formless sphere (arūpāvacara) as wholesome (kusala)? How does one define them as indeterminate (abyākata)? One defines the four attainments (samāpatti) of the formless sphere belonging to one established here as wholesome; one defines the four attainments of the formless sphere belonging to one reborn there as indeterminate. Thus one defines dhammas belonging to the formless sphere as wholesome and defines them as indeterminate.
