Dhammapada · 25.8

Sabbaso nāmarūpasmiṃ, yassa natthi mamāyitaṃ;Asatā ca na socati, sa ve bhikkhūti vuccati.

Sabbaso namarupasmim, yassa natthi mamayitam; Asata ca na socati, sa ve bhikkhuti vuccati.

In whom there is no 'mine-making' anywhere in mind-and-body, and who does not grieve over what is not — he indeed is called a bhikkhu.
