We are on a journey to a more blessed life. Let us not, along the way, be angry with one another. Instead let us go forward with our fellow travelers, our brothers and sisters, gently, in peace and in love. And whatever happens along the way, however great the provocation, do not let anger into your heart.
Take with you the advice of Joseph when he bid his brothers good-bye: "be not angry along the way." Don't let anger get the smallest foothold in your heart. Exclude absolutely, as Augustine advises, even its slightest presence, however justified and reasonable it may seem. For once it gets into your heart it is hard to uproot. A mote rapidly becomes a beam. It will stay with you and if you ignore the apostle Paul's advice, and let the sun go down on your anger, it will harden into hatred.
Constantly fed by imaginings and delusions, it will become all but impossible to set yourself free of it. It is best to avoid all anger rather than try to come to terms with it; for if we give anger an inch it will surely take a mile.
Be not angry along the way.
(Set Your Heart Free, The Practical Spirituality of Francis de Sales)
