This is a wonderful book. It may have been meant more for clergy even though most of the prayers are for personal benefit. The reason I say it may be more for the clergy is this book greatly details what an indulgence is and the conditions surrounding it. But it is full of information and prayers for lay people also. For example, did you know that just by making a proper Sign of the Cross (In the Name of the Father...) there is an indulgence attached to it? I myself tried to plow through all the "rules" but finally went right to the prayers. All in all, it is an excellent resource.
