A Worthwhile Purchase
Fr. Boyle wrote a series of books based on conferences to religious. Each chapters covers one topic, e.g.humility, purity, Love of God, presumption, etc. Written in a very easy to read style with memorable quotes. Can be beneficially re-read many times. Each chapter is 20 pages or less. Other titles by him (I have a number of them) are in the same style, but on different topics.
