The Spiritual Life: A Treatise on Ascetical and Mystical Theology written by Very Rev. Adolphe Tanqueray S.S.D.D. is very well written and is used intensely at our Confraternity of Mary Immaculate Queen monthly meetings. It is highly recommended by our moderator and Pastor, Fr. Casimir Puskorious and by its members. It is in my library as well, for review of meeting materials.
