Oh, the sweetness of the Jesus Prayer or Efche (sometimes simply called “the prayer”). This prayer has bred many saints. But the Fathers in the Philokalia admonish us (as well as many other experienced hesychastic elders), not to begin the Prayer by trying breathing/sitting techniques as prescribed in many books (that in my opinion should only be available to the public under the guidance of an experienced geronda/elder) without having an experienced elder. We are warned that improper practice can lead to severe spiritual damage. I am in no way any type of Elder or teacher, but from what I have read/been taught, it is more practical for a lay person to begin the Prayer by setting aside a certain amount of time each day to practice the prayer. Try not to let your mind wander, but if it does don’t panic, just calmly return your focus to the words of the prayer. The devil will try many ways to stop you from say the Prayer, but you must persist. Don’t try to engage the evil one if he tries to distract you, but simply return to the prayer focusing on the words you are saying to God only. If you allow the evil one to get you to engage him, or turn your thoughts to something else then he has accomplished his goal. No matter how many times your thoughts wander, simply and calmly reign them back in to the words of the Prayer. Find an experienced Spiritual Elder to guide you in the Prayer and to help set a rule for you. Normally this person should be your Father-Confessor. I believe with my whole heart, that if every Christian, whether Orthodox, Roman Catholic or even protestant would learn the Prayer and practice it diligently, with love and patience and under guidance from an experienced Geronda/Elder, that union between us all would be impossible to avoid, because the Prayer causes us to set aside our pride and acknowledge that we are all sinners in need of the mercy of our Lord Jesus Christ!
The sinner,
Josh
Lord Jesus Christ, Son of God, have mercy on me, a sinner!
Most Holy Mother of God save us!
