The Monk Savva Storozhevsky, Zvenigorodsky in his early youth left the world, having accepted the tonsure from the Monk Sergius of Radonezh, and was one of his first disciples and associates. The monk loved a silent life, avoided conversations with people and was in constant labor, weeping over the poverty of his soul, remembering the judgment of God.

The Monk Savva for all people was an image of simplicity and humility, he acquired such deep spiritual wisdom that even "in the monastery of Sergius he was a confessor to the whole brotherhood, a venerable and highly instructive elder." When the Grand Duke Dimitry Donskoy, in gratitude for the victory over Mamai, set up a monastery of the Dormition of the Mother of God on the Dubenka River, Savva became its abbot, with the blessing of St. Sergius.
