Believe nothing merely because you have been told it, or because it is tradition, or because you yourself have imagined it. Do not believe what your teacher tells you merely out of respect for him. But whatever, after due examination and analysis, you find to be conducive to the good, the benefit, the welfare of all beings, believe and cling to that doctrine, and take it as your guide.
— Buddha
Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned.
