He was born in Egypt around the year 300. After receiving a vision in a dream, his mother consecrated him to God as a monk, and he became a disciple of Abba Pambo (July 18) when scarcely more than a child. He was a fellow-disciple with St John the Dwarf (November 9), who later wrote his life. Païsius excelled in ascetical labors, and was granted many revelations. Once the Prophet Jeremiah, whom he especially venerated, appeared to him. At another time the Lord himself appeared to him with two Angels, and allowed Païsius to wash His feet. He was granted a special gift of being able to live without food: He often went without food for two weeks, and once, according to St John the Dwarf, for seventy days. He underwent terrible struggles with the demons, who sometimes appeared to him in horrible forms and sometimes as angels of light. He was once asked what virtue is the highest of all, and answered "That which is done in secret." He reposed in peace at a great age. His relics can still be venerated at the monastery of Amba Bishoy in Wadi Natrun in Egypt, where they still work healings and other miracles.
