Prayer is food for the soul. Do not starve the soul, it is better to let the body go hungry… ~ St. Joseph of Optina
You don’t have a soul. You are a soul. You have a body. ~C. S. Lewis
Through greed we underwent the first stripping, overcome by the bitter tasting of the fruit, and we became exiles from God. But let us turn back to repentance and, fasting from the food that gives us pleasure, let us cleanse our senses on which the enemy makes war. Let us strengthen our hearts with the hope of grace, and not with foods which brought no benefit to those who trusted in them. Our food shall be the Lamb of God, on the holy and radiant night of His Awakening: the Victim offered for us, given in communion to the disciples on the evening of the Mystery, who disperses the darkness of ignorance by the Light of His Resurrection. ~ Aposticha, Vespers – evening of Sunday of the Last Judgement
Do that which is good, and no evil shall touch you. Prayer is good with fasting and alms and righteousness. A little with righteousness is better than much with unrighteousness. It is better to give alms than to lay up gold: For alms doth deliver from death, and shall purge away all sin. Those that exercise alms and righteousness shall be filled with life: But they that sin are enemies to their own life. ~ Archangel Raphael, Tobit 12:7-10
One should not think about the doings of God when one’s stomach is full; on a full stomach there can be no vision of the Divine mysteries. ~St. Seraphim of Sarov
It is necessary for a Christian to fast, in order to clear his mind, to rouse and develop his feelings, and to stimulate his will to useful activity. These three human capabilities we darken and stifle above all by ‘surfeiting, and drunkenness, and cares of this life’ (Lk. 21:34). ~ St. John of Kronstadt
Many human activities, good in themselves, are not good because of the motive for which they are done. For example, fasting and vigils, prayer and psalmody, acts of charity and hospitality are by nature good, but when performed for the sake of self-esteem they are not good. ~ St. Maximos the Confessor
Devils take great delight in fullness, and drunkenness and bodily comfort. Fasting possesses great power and it works glorious things. To fast is to banquet with angels. ~ St. Athanasius the Great
Let the mouth also fast from disgraceful speeches and railings. For what does it profit if we abstain from fish and fowl and yet bite and devour our brothers and sisters? The evil speaker eats the flesh of his brother and bites the body of his neighbour. ~St. John Chrysostom
