John lived a life of asceticism in the so-called "old caves," the "old Lavra" of Chariton the Great in Palestine. Having loved Christ the Lord with all his heart, with all his soul and with all his mind, John, at an early age, began to travel to the holy places and to listen to the instructions and counsels of the holy men. Finally, he settled in the Caves of Chariton, where he gave himself to rigorous asceticism spending days and years in fasting, prayer, vigils, continuously meditating on death, and teaching himself humility. As a good ripened fruit, he was plucked by death and took up habitation in Paradise. He lived and died in the eighth century.
