Not only should we observe moderation with food, but we must also abstain from every other sin so that just as we fast with our stomach, we should fast with our tongue. Likewise, we should fast with our eyes; i.e. not look at agitating things, not allow your eyes freedom to roam, not to look shamelessly and without fear. Similarly, arms and legs should be restrained from doing any evil acts.
Dorotheus of GazaIf a man really sets his heart upon the will of God, God will enlighten a little child to tell that man what is His will. But if a man does not truly desire the will of God, even if he goes in search of a prophet, God will put into the heart of the prophet a reply like the deception in his own heart.
Dorotheus of GazaNo one who lies is linked to God. God is the truth. He says, 'I am the Way, the Truth and the Life' (Jn. 14:6). See how we sort ourselves out and what position we take up through lying ? clearly on the side of the evil one. If, therefore, we want to be saved, we must with all our hearts love the Truth and guard ourselves from every kind of falsehood so that we may not be separated from truth and from life.
Dorotheus of GazaA man who gives way to his passions is like a man who is shot by an enemy, catches the arrow in his hands, and then plunges it into his own heart. A man who is resisting his passions is like a man who is shot by an enemy, and although the arrow hits him, it does not seriously wound him because he is wearing a breastplate. But the man who is uprooting his passions is like a man who is shot by an enemy, but who strikes the arrow and shatters it or turns it back into his enemies heart.
