Mahāviyūhasuttaniddesa

Suttapiṭaka · Khuddakanikāya · Mahāniddesa · Vol. 29 · Section 620

[620] If one has fallen away from virtue and vows (sīlavata), he trembles, having failed in his task (kamma); he yearns and longs for purity (suddhi), like one who, journeying away from home, is bereft of his caravan.
