Ascetic life
Paisius trained in the Egyptian sketes under Saint Pambo (commemorated July 18), known for strict obedience and fasting. As one feat of self-discipline he is said to have kept his eyes cast downward for three years to guard his senses.
His fasting was extreme. According to the synaxarion he progressed from going without food for a week, then two weeks; on occasion, after partaking of the Holy Mysteries of Christ, he is said to have survived without food for seventy days.
Withdrawing into the Nitrian desert in search of solitude, he lived in a cave carved by his own hands. A number of monks and laymen gathered around him, and a monastery was established under his spiritual fatherhood.
