Johannes Tauler : (3) " Because in the school of the Spirit man learns wisdom through humility, knowledge by forgetting, how to speak by silence, how to live by dying. " - Johannes Tauler " Such sins, even if they do not kill all grace in us, do harm, nevertheless; and though they are only venial in themselves, they make us apt, ready, and inclined to lose grace and to fall into mortal sin. " - Johannes Tauler " Give yourself entirely to God, enter and hide in the hidden ground of your soul. " - Johannes Tauler
