[40] At Sāvatthī. There indeed … "Bhikkhus, form (rūpa) is suffering (dukkha); feeling (vedanā) is suffering; perception (saññā) is suffering; volitional formations (saṅkhārā) are suffering; consciousness (viññāṇa) is suffering. Seeing thus … he understands: '… there is no more coming back to this state of being.'"
