Dukkhasutta

Suttapiṭaka · Saṁyuttanikāya · Khandhavaggasaṁyutta · Vol. 17 · Section 280

[280] "And what, bhikkhus, is suffering (dukkha)? It should be said: the five aggregates subject to clinging (pañcupādānakkhandhā). What five? Namely: the aggregate of form (rūpa) subject to clinging … the aggregate of consciousness (viññāṇa) subject to clinging. This, bhikkhus, is called suffering."
