This collection of five books contains F?nelon's outstanding teachings on prayer, suffering, the achievement of virtue, and other spiritually crucial tenets. Uniting aspects of philosophy with Christian theology and spiritualist thought, F?nelon presents here a lively set of treatises where esoteric knowledge and concepts are put to singular good purpose: enhancing and informing the spiritual life of the reader. Although at times arcane, the advice given is rooted in the Christian tradition and scriptures. F?nelon never attained mainstream popularity as an author during or after his life, however he was and remains a favorite of scholars and religious adherents seeking to explore the deepest channels of their faith. Although more difficult than other inspirational authors, F?nelon's authenticity and depth cannot be doubted.
