Anger is the function of expectation (for example, if I go into a store and they don’t give me a chocolate, I won’t be angry; but if I go into a store and they give everyone chocolates, BUT me !!!!) so if we change our exceptions, namely that all comes through man from God! (unbeknown to man) hence, like Josef, even if our own brothers sell us as a slave, we can live, thrive, love and be kind.
