Dhammapada · 25.14

Suññāgāraṃ paviṭṭhassa, santacittassa bhikkhuno;Amānusī ratī hoti, sammā dhammaṃ vipassato.

Sunnagaram pavitthassa, santacittassa bhikkhuno; Amanusi rati hoti, samma dhammam vipassato.

For the bhikkhu of peaceful mind who has entered an empty dwelling, who rightly contemplates the Dhamma — there arises a more-than-human joy.
