Hesychastic Prayer

It comprises a twofold exercise, omphaloskepsis and indefinite repetition of the Prayer of Jesus: “Lord Jesus Christ, Son of God, have mercy on me!” By sitting in darkness, bowing the head, fixing the eyes on the center of the abdomen (in other words, the navel), trying to discover the place of the heart, by repeating this exercise indefatigably and always accompanying it with the same invocation, in harmony with the rhythm of respiration, which is retarded as much as possible, one will, if one perseveres day and night in this mental prayer, end by finding what one sought, the place of the heart, and, with it and in it, all kinds of wonders and knowledge.

— Father Irénée Hausherr
