Dhammapada · 20.5

Sabbe saṅkhārā aniccāti, yadā paññāya passati;Atha nibbindati dukkhe, esa maggo visuddhiyā.

Sabbe sankhara aniccati, yada pannaya passati; Atha nibbindati dukkhe, esa maggo visuddhiya.

'All conditioned things are impermanent' — when one sees this with wisdom, then one turns away from suffering. This is the path to purification.
