237. Thy life has come to an end, thou art come near to death (Yama), there is no resting-place for thee on the road, and thou hast no provision for thy journey.
238. Make thyself an island, work hard, be wise! When thy impurities are blown away, and thou art free from guilt, thou wilt not enter again into birth and decay.
239. Let a wise man blow off the impurities of his self, as a smith blows off the impurities of silver one by one, little by little, and from time to time.
DHAMMAPADA, Chapter 18. Impurity
