Ascetic Discipline
Pimen's epithet, 'the Faster,' reflects the rigor of his abstinence. Accounts state that he restricted himself to the most necessary quantity of food, and that this bodily fasting was the outward sign of an interior watchfulness, guarding against any action, thought, or feeling displeasing to God.
Tradition holds that despite so severe a regimen he retained the strength for the demanding manual labor of the monastery, joining physical work with vigils of nocturnal prayer.
