Bāhirāyatanadukkhasutta  The Exterior as Suffering

“Rūpā, bhikkhave, dukkhā. Saddā … gandhā … rasā … phoṭṭhabbā … dhammā dukkhā.  “Mendicants, sights, sounds, smells, tastes, touches, and ideas are suffering.

Evaṁ passaṁ …pe…  Seeing this …
nāparaṁ itthattāyāti pajānātī”ti.  They understand: ‘… there is nothing further for this place.’”
