Fasting according to an Eastern Father

 "Let thy mind fast from vain thoughts; let thy memory fast from remembering evil; let thy will fast from evil desire; let thine eyes fast from bad sights: turn away thine eyes that thou mayest not see vanity; let thine ears fast from vile songs and slanderous whispers; let thy tongue fast from slander, condemnation, blasphemy, falsehood, deception, foul language and every idle and rotten word; let thy hands fast from killing and from stealing another's goods; let thy legs fast from going to evil deeds: Turn away from evil, and do good."

Saint Tichon of Zadonsk
