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 BuddhaDo not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders.
Gautama Buddha
