Truly blessed is he who cleaves with his thought to the Prayer of Jesus, constantly calling to Him in his heart, just as air cleaves to our bodies or the flame to the candle. The sun, passing over the earth, produces daylight ; the holy and worshipful Name of Lord Jesus, constantly shining in the mind, produces a measureless number of sun-like thoughts.
St. Hesychius of Jerusalem, On Sobriety and Prayer, The Philokalia
*Fr. P’s note: Often in Orthodox circles, the Prayer of Jesus, or The Jesus Prayer is referred to simply as “The Prayer”. It is not the case in this quote, but I thought it might be good to note.
