This new edition of Prayer of the Heart brings back into print a pioneering work that sold almost 70,000 copies in its first edition. George Maloney, S.J. (1924-2005), a leading exponent of the Eastern Christian spiritual tradition in the decades after Vatican II, opens up the Eastern Christian tradition of prayer--in particular the Jesus Prayer--to Western Christians in a clear and practical manner. Unmatched as a readable and comprehensive guide to Eastern spirituality during its fifteen-year history of publication, it fills a void in the spirituality market for today's readers as well.
