Abba Pitirim directed a group of ascetics who led a very austere life in the arid mountains of the Thebaid. He was himself a disciple and third successor of Saint Anthony the Great (17 Jan.) in his hermitage. He ate no more than a little flour mixed with water twice a week, and so persevered in spiritual labours that he gained abundant graces from the Holy Spirit. Among other things, he taught that to each passion there corresponds a demon who tries to stir up that passion within us through different temptations. In order to get rid of these demons and of evil thoughts, Abba Pitirim said that we must first free our hearts from passions.
