He who understands the unreality of all things

Yesaṃ sannicayo natthi, ye pariññātabhojanā;

Suññato animitto ca, vimokkho yesaṃ gocaro;

Ākāse va sakuntānaṃ , gati tesaṃ durannayā.

He who understands the unreality of all things,

and who has laid up no store,

his track is unseen,

like that of birds in the air.

Dhammapada, 92.
