After 19 years of monasticism, Saint John of the Ladder (Climaticus) lived in the wilderness for 40 years, practicing silence, fasting, prayer, and penitence. "I do not fast excessively, nor do I give myself over to intense all-night vigil, nor lay upon the ground, but restrain myself, and the Lord soon saved me." At 75 he became hegumen of Sinai Monastery and was asked to write something for the monks. This was "The Ladder of Divine Ascent," a 30-step exercise of soul purification. (Mar 30)
