“Bhikkhus, these three feelings are impermanent, conditioned, dependently arisen, subject to destruction, subject to vanishing, subject to fading away, subject to cessation. What three? Pleasant feeling, painful feeling, neither-painful-nor-pleasant feeling. These three feelings are impermanent, conditioned, dependently arisen, subject to destruction, subject to vanishing, subject to fading away, subject to cessation.” sn.iv.215
