Your enemy, the evil one, the father of lies, does not slumber; and endeavors, by every means open to him, to harden your heart — to make it false and crafty, to drive out from it faith and hope in God – together with love for Him and love and sympathy for your neighbor – and to occupy you with worldly, temporal interests. Watch yourself, watch the thoughts of your heart, and do not bind yourself in the chains of worldly desires and pleasures. Let your happiness be in the one God and the human soul.
