Dhammapada 32 [Khuddaka Nikaya]

II- Appamadavagga, Heedfulness
9 - Nigamavasitissatthera Vatthu

Appamadarato bhikkhu, pamade bhayadassi va;
abhabbo parihanaya, nibbanasseva santike.

32: A bhikkhu who takes delight in mindfulness and sees danger in negligence will not fall away; he is, indeed, very close to Nibbana.
