Monastic Formation
According to his Life, Paul was born at Moscow in 1317 into a wealthy household that prepared him for a secular career, but he inclined from youth toward piety and care for the poor. At twenty-two he left home secretly and was tonsured a monk at the Nativity monastery on the Volga, in the Yaroslav diocese.
He subsequently came to the Holy Trinity monastery of Saint Sergius of Radonezh, where he lived for several years as Sergius's disciple in obedience to the elder. With Sergius's blessing he then took up the life of a hermit in a separate cell a short distance from the monastery, remaining there for fifteen years.
