Drawing from the spiritual current of Celtic tradition, which encompassed all aspects of daily life with prayer and invocation, and from Celtic Christianity, Celtic Devotional combines traditional blessings with specially written prayers and meditations. Many new prayers, blessings, and ceremonies appear in this revised edition of a much-loved book.

The marking of time by prayer or special periods of devotion is common to all spiritualities. This book follows the seasonal pattern of the Celtic world. It is divided into five sections; the first four correspond to the Celtic seasonal quarters of the year. The last one contains prayers and blessings for special occasions.
