Dukkhasutta

Suttapiṭaka · Saṁyuttanikāya · Khandhavaggasaṁyutta · Vol. 17 · Section 381

[381] At Sāvatthī. Sitting to one side, the Venerable Rādha said this to the Blessed One: "Venerable sir, it is said, 'suffering (dukkha), suffering.' What now, venerable sir, is suffering?" "Form (rūpa), Rādha, is suffering; 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 for this state of being.'"
