Hesychios the Priest: On Personal Holiness
“Just as it is impossible to fight battles without weapons, or to swim a great sea with clothes on, or to live without breathing, so without humility and the constant prayer to Christ it is impossible to master the art of inward spiritual warfare or to set about it and pursue it skillfully.” [On Watchfulness and Holiness, 99]
“Prayer is a great blessing, and it embraces all blessings, for it purifies the heart, in which God is seen by the believer.” [Watchfulness, 62]
“The more the rain falls on the earth, the softer it makes it. Similarly, Christ’s holy name gladdens the earth of our heart the more we call upon it.” [Watchfulness, 41]
