Dhammapada 38-39 [Khuddaka Nikaya]

3 - Cittavagga, The Mind
5 - Cittahatthatthera Vatthu

Anavatthitacittassa, saddhammam avijanato;
pariplavapasadassa, panna na paripurati.
Anavassutacittassa, ananvahatacetaso;
punnapapapahinassa, natthi jagarato bhayam.

38: If a man's mind is unsteady, if he is ignorant of the true Dhamma, and if his faith is wavering, then his knowledge will never be perfect.
39: If a man's mind is free from passion, if he is free from ill will, if he has abandoned both good and evil, and if he is vigilant, for such a man there is no danger.
