Monastic Formation and Withdrawal
The life presents Sabbatius as a monk drawn repeatedly toward deeper solitude. His tonsure at the Kirillo-Belozersky monastery in 1396 placed him within one of the principal centers of northern Russian monasticism, where his discipline and gentleness toward the brethren were noted. As the attention of others grew, he sought a more secluded setting at Valaam on Lake Ladoga, and finally pursued the still more remote wilderness of the White Sea islands.
By tradition, Sabbatius departed Valaam by night to avoid being held back, and made his way to the shores of the White Sea. From there he crossed to Solovki, an uninhabited island lying a journey of several days by boat from the mainland.
