Dhammapada 13-14 [Khuddaka Nikaya]

I- Yamakavagga, The Pairs
9- Nandatthera Vatthu

Yatha agaram ducchannam, vutthi samativijjhati;
evam abhavitam cittam, rago samativijjhati.

Yatha agaram suchannam, vutthi na samativijjhati;
evam subhavitam cittam, rago na samativijjhati.

13: Just as rain penetrates a badly-roofed house, so also, passion (raga) penetrates a mind not cultivated in Tranquillity and Insight Development (Samatha and Vipassana).
 
14: Just as rain cannot penetrate a well-roofed house, so also, passion (raga) cannot penetrate a mind well-cultivated in Tranquillity and Insight Development (Samatha and Vipassana).
