Among all sins, there is one which completely opposes the major blessing of human life, which is your love for your brother: there is no worse sin than to destroy this major joy of life, by feeling rage and hatred for your brother.
Seneca, a wise man from Rome, said that when you want to escape from your rage, when you feel that it grows, the best thing to do is to stop. Do not do anything: do not walk, do not move, do not speak. If your body or your tongue moves at this moment, then your rage will grow.
Rage is very harmful for all people, but it is most harmful for the man who experiences it.
An evil person damages not only others but himself.
