"Lord Jesus Christ, Son of God, have mercy on me, a sinner."
The Jesus Prayer is an ancient prayer, going back to Diadochos in the late fifth or early sixth century. It is an example of an "arrow prayer" (to "assault" heaven), a practice going back to monks in fourth century Egypt in Nitria. The prayer is a way of opening our hearts to God, a way we can, as St. Paul urges us, "pray ceaselessly," Repetition of the prayer can lead to an inner silence, called hesychia.
We explored the Jesus Prayer in a single session based on an audio CD of a lecture on the Jesus Prayer by Dr. Albert Rossi. The original presentation was tied to audio clips from the CD; these audio clips are not available in the download version. The presentation was by David Monyak.
