Fasting is the soul of prayer; mercy is the lifeblood of fasting. Let no one try to separate them; they cannot be separated. If you have only one of them or not all together, you have nothing. So, if you pray, fast; if you fast, show mercy; if you want your petition to be heard, hear the petition of others. If you do not close your ear to others, you open God’s ear to yourself. St. Peter Chrysologus
”Enter the inner chamber of your soul, shut out everything except God and that which can help you in seeking him, and when you have shut the door, seek him.” – St. Anselm of Canterbury
