Thus has Thomas Merton described St. John of the Cross, echoing the considered judgment of most authorities on the spiritual life; and here in this volume is the great mystic’s most widely appealing work. Ascent of Mount Carmel is an incomparable guide to the spiritual life — because its author has lived his own counsel. Addressed to informed Christians who aspire to grow in union with God, it examines every category of spiritual experience, the spurious as well as the authentic. With rare insight into human psychology it not only tells how to become more closely united with God, but spells out in vivid detail the pitfalls to avoid.
