The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
From this patience there spring meekness and kindliness, for none can be meek in adversity save the patient man.
Meekness gives a man peace and rest in all things. For the meek man can bear provoking words and ways, uncivil looks and deeds, and every kind of injustice towards himself and his friends, and yet in all things remain in peace, for meekness is peaceful endurance.
By meekness the irascible or repulsive power remains unmoved, in quietude; the desirous power is uplifted toward virtue; the rational power, perceiving this, rejoices. And the conscience, tasting it, rests in peace; for the second mortal sin, Anger, fury, or wrath, has been cast out. For the Spirit of God dwells in the humble and the meek; and Christ says: Blessed are the meek, for they shall inherit the earth, that is, their own nature and all earthly things, in meekness; and after that the Country of Life in Eternity.
