“'No one can or should halt sacrifice. Sacrifice is not destruction, sacrifice is the foundation stone of what is to come. Have you not had monasteries? Have not countless thousands gone into the desert? You should carry the monastery in yourself. The desert is within you. The desert calls you and draws you back, and if you were fettered to the world of this time with iron, the call of the desert would break all chains. Truly, I prepare you for solitude.'”
