If a man does not argue with the thoughts that the enemy secretly sows in us, but by prayer to God uproots conversation with them, this is a sign that his mind has attained wisdom, and that he has found a short path.
Isaac of NinevehIf you are truly merciful, then when what is yours is unjustly taken, don't be sad inside, and do not tell of our loss to your neighbor. Let a better loss, inflicted by those who insult you, be absorbed by your mercy.
Isaac of NinevehA man who is truly humble is not troubled when he is wronged and he says nothing to justify himself against the injustice, but he accepts slander as truth; he does not attempt to persuade men that he is calumniated, but he begs forgiveness.
Isaac of NinevehLet there always be a preponderance of mercy with you, even though you don't feel such mercy in yourself, as God has for the world ... A cruel and merciless heart is never purified. A merciful man is the doctor of his own soul, because as it were a by a strong wind from is heart he drives out the darkness of the passions.
