Book excerpt: This manual of devotion consists of a series of chapters or instructions upon important points of Christian teaching which Saint Alphonsus calls "Considerations". As the Saint describes, "These Considerations are written for the purpose of pricking or of wounding the conscience... that so it may be thoroughly aroused and awakened." The Considerations deal with such doctrines and facts as have a universal application, which admit of no dispute, and which are always confirmed by some passage from Holy Scripture. Preparation for Death is essentially a guide to prayer. It represents, from its beginning to its end, the continual outpouring of heart before God, an outpouring that is at times expressed in the very same words which imply a new phase of thought. Regarded as a Manual of Mental Prayer, each of these "Considerations" has a technical and special signification. They treat of life and death, the value of time, the mercy of God, the habit of sin, the general and particular judgments, the love of God, Holy Communion, and other subjects equally important.
