The grudge you hold on to is like a hot coal that you intend to throw at someone, only you're the one who gets burned.
Gautama BuddhaTherefore, be ye lamps unto yourselves, be ye a refuge to yourselves. Hold fast to the truth as a lamp; hold fast as a refuge to the truth. Look not for refuge to anyone besides yourselves.
Gautama BuddhaThose who are truly wise will remain unmoved by feelings of happiness and suffering, fame and disgrace, praise and blame, gain and loss.They will remain calm like the eye of a hurricane.
Gautama Buddha
