252. The fault of others is easily perceived, but that of oneself is difficult to perceive; a man winnows his neighbour’s faults like chaff, but his own fault he hides, as a cheat hides the bad die from the gambler.
253. If a man looks after the faults of others, and is always inclined to be offended, his own passions will grow, and he is far from the destruction of passions.
DHAMMAPADA, Chapter 18. Impurity
