‘For many generations thousands of the most gifted and exemplary human beings have been devoting all their energies of mind and body to becoming holy; on the way they have let fall many crumbs of wisdom; it is a privilege, as well as a joy, to pick up those crumbs and recycle them.’Holiness cannot be taught by any kind of trick or technique and can only be truly understood through a personally transformative process, explains theological writer and professor Donald Nicholl in this classic work, which arose first from a series of conferences that he gave to a community of Poor Clares.The Pocket Library of Spiritual Wisdom comprises some of the very best Christian writing published by Darton, Longman and Todd since its foundation in 1959.
