"It is understood that since the reason for entering the poustinia is one of listening to God in prayer and fasting, the first act of the poustinik is to fold the wings of his intellect and open the doors of his heart. The Russians would say: Put your head into your heart and try to achieve a deep and profound interior silence. It is then, when one is deeply silent, that God begins to speak."
Dom Lorenzo Scupoli
“For whoever has the courage to conquer his passions, to
subdue his appetites, and repulse even the least motions of his own will,
performs an action more meritorious in the sight of God than if, without this,
he should tear his flesh with the sharpest disciplines, fast with greater austerity
than the ancient Fathers of the Desert, or convert multitude of sinners.”
