Reflection: The holy fathers taught us to be "killers of passions and not killers of the body". True fasting means the hands and feet are kept from every evil action and the eyes do not look at vain things.
Practice: Choose one "vain thing" you typically look at (social media, entertainment) and replace that time with reading the lives of the saints.
The Orthodox Faith - Volume IV - Spirituality - Prayer, Fasting, and Almsgiving - Fasting - Orthodox Church in America: “Saint Isaac of Syria says, “Meager food at the table of the pure cleanses the soul of those who partake from all passion ... for the work of fasting and vigil is the beginning of every effort against sin and lust ... almost all passionate drives decrease through fasting.”
For the holy fathers taught us to be killers of passions and not killers of the body. Partake of everything that is permissible with thanksgiving, to the glory of God and to avoid boastful arrogance; but refrain from every excess (The Monks Callistus and Ignatius, 14th c., Directions to Hesychasts).”
“Fasting in the body, O brethren, let us also fast from sin.” This is the Church's song in the lenten season of fasting. It is also the teaching of the saints.
... in fasting one must not only obey the rule against gluttony in regard to food, but refrain from every sin so that, while fasting, the tongue may also fast, refraining from slander, lies, evil talking, degrading one's brother, anger and every sin committed by the tongue. One should also fast with the eyes, that is, not look at vain things ... not look shamefully or fearlessly at anyone. The hands and feet should also be kept from every evil action.”
Life of the Saint, The Dormition of our Most Holy Lady the Mother of God and Ever-Virgin Mary - Orthodox Church in America: “When did She ever hurl the least insult in the face of Her parents? When was She at discord with Her kin? When did She ever puff up with pride before a modest person, or laugh at the weak, or shun the destitute? With Her there was nothing of glaring eyes, nothing of unseemly words, nor of improper conduct. She was modest in the movement of Her body, Her step was quiet, and Her voice straightforward; so that Her face was an expression of soul. She was the personification of purity.
“All Her days She was concerned with fasting: She slept only when necessary, and even then, when Her body was at rest, She was still alert in spirit, repeating in Her dreams what She had read, or the implementation of proposed intentions, or those planned yet anew. She was out of Her house only for church, and then only in the company of relatives. Otherwise, She seldom appeared outside Her house in the company of others, and She was Her own best overseer. Others could protect Her only in body, but She Herself guarded Her character.”
