I was disturbed to see that Logos will be including Fr. Keating's works on prayer. Although he seems to be well-intentioned and has acquired a large following over the years, his ideas are not regarded as orthodox or safe by spiritual directors who are grounded in authentic Catholic spirituality. There is a distinct New Age influence within his teaching.
I implore everyone who is interested in this author to first get some perspective from other reliable Catholic sources, such as Catholic Answers (www.catholic.com) or Dan Burke at Roman Catholic Spiritual Direction (www.rcspiritualdirection.com). Father Thomas DuBay was adamantly opposed to the practice of Centering Prayer as unsafe and opposed to authentic advancement in prayer.
According to these sources, following Fr. Keating's methods will at best bring hamstring a soul in her quest for spiritual union with God; other more ominous problems can arise.
I hope that Logos will consider withdrawing these unsound writings from its library.
