fasting and mercy

 "Fasting is the soul of prayer, mercy is the lifeblood of fasting. 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

*but don't be fasting on Sunday.  :)
