The cessation of dukkha
The third noble Truth, the cessation of dukkha, is nibbana. At the attainment of
enlightenment nibbana, the unconditioned reality, is experienced. Citta, cetasika
and rupa are conditioned realities which arise and fall away, they are dukkha.
Nibbana is the ultimate reality which is unconditioned, it does not arise and fall
away, it is not dukkha. Nibbana is the end of unsatisfactoriness inherent in all
conditioned realities which arise and fall away.
