[905] Which phenomena (dhammā) are not roots (hetu) but accompanied by roots (sahetuka)?
The wholesome (kusala) in the four planes (bhūmi); the unwholesome (akusala); the resultant (vipāka) in the four planes, setting aside the rootless (ahetuka) arisings of mind (cittuppāda) from among the resultants of the sense sphere (kāmāvacara); the functional (kiriyā) indeterminate (abyākata) in the three planes, setting aside the rootless arisings of mind from among the sense-sphere functionals; setting aside the roots arisen herein — these phenomena are not roots but accompanied by roots.
Which phenomena are not roots and rootless?
The two sets of fivefold consciousness (pañcaviññāṇa), the three mind elements (manodhātu), the five rootless mind-consciousness elements (manoviññāṇadhātu), form (rūpa), and Nibbāna — these phenomena are not roots and rootless.
Phenomena that are roots should not be said to be "not roots but accompanied by roots," nor "not roots and rootless."
