Yassa selūpamaṃ cittaṃ, ṭhitaṃ nānupakampati,
virattaṃ rajanīyesu,
kopaneyye na kuppati:
Yassevaṃ bhāvitaṃ cittaṃ,
kuto taṃ dukkhamessatī?

Whose mind is like rock, steady, unmoved,
dispassionate for things that spark passion,
unangered by things that spark anger:
When one’s mind is developed like this,
from where can there come suffering & stress?

Udāna 4.34
Translated from Pāli by Thanissaro Bhikkhu
