[202] Therein, what is suffering (dukkha)?
The remaining defilements (kilesa); the remaining unwholesome phenomena (dhammā); the three wholesome roots (kusalamūla) that are subject to taints (sāsava); the remaining wholesome phenomena that are subject to taints; the results (vipāka), subject to taints, of wholesome and unwholesome phenomena; whatever phenomena are functional (kiriyā), neither wholesome nor unwholesome and not results of kamma; and all form (rūpa) — this is called suffering.
