Dhamma Verses (Dhammapada, KN 2)

1: The Chapter about the Pairs – 24
Skilful means
The Buddha’s half-brother Nanda ordained, but yearned for
the lay-life; the Buddha promised him celestial sprites as a
reward for his efforts in the spiritual life; Nanda put forth
effort and became an Arahat, and the Buddha was released
from his promise; these verses were spoken about him.
13. Yathā agāraṁ ducchannaṁ vuṭṭhī samativijjhati,
evaṁ abhāvitaṁ cittaṁ rāgo samativijjhati.
Just as the rain can penetrate
a house with thatching that is poor,
so also passion penetrates
a mind that is undeveloped.
14. Yathā agāraṁ succhannaṁ vuṭṭhī na samativijjhati,
evaṁ subhāvitaṁ cittaṁ rāgo na samativijjhati.
Just as rain does not penetrate
a house with thatching that is good,
so passion cannot penetrate
a mind that is well-developed.
