The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
From the renunciation of self-will springs patience; for none can be perfectly patient in all things save the man who has subjected his own will to the will of God, and also in all profitable and seemly things, to the will of all other men.
Patience is a peaceful endurance of all things that may befall a man either from God or from the creatures. Nothing can trouble the patient man; neither the loss of earthly goods, of friends and kinsmen, nor sickness, nor disgrace, nor life, nor death, nor purgatory, nor devil, nor hell. For he has abandoned himself in perfect charity to the will of God, and as he is not burdened by mortal sin, everything that God imposes on him, in time and in eternity, is light to him. By this patience a man is also adorned and armed against peevishness and sudden wrath, and impatience in suffering; which often stir a man from within and from without, and lay him open to many temptations.
