Currently I am reading Meeting Christ in His Mysteries: A Benedictine Vision of the Spiritual Life, by Gregory Collins OSB, a monk of Glenstal Abbey in Ireland. Although a Benedictine, he speaks generously from the perspective of Eastern Orthodoxy, of which the Jesus Prayer is important.
Collins tells me, “There is nothing selfish about such sustained personal prayer (the Jesus Prayer) for it is really a kind of evangelization of the self,” and with that I am encouraged to keep saying it.
