If 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 NinevehWhoever prematurely begins a work that is above his strength receives nothing, but only brings harm upon himself.
Isaac of NinevehThe soul that loves God has its rest in God and in God alone. In all the paths that men walk in in the world, they do not attain peace until they draw nigh to hope in God.
Isaac of NinevehThe beginning of divine wisdom is clemency and gentleness, which arise from greatness of soul and the bearing of infirmities.
Isaac of NinevehIt is impossible to draw near to God without sorrows, without which human righteousness cannot remain unchanged... If you desire virtue, than give yourself to every affliction, for afflictions produce humility. If someone abides in virtue without afflictions, the door of pride is opened to him.
