“I had heard bad things about this book many years ago. Particularly that a lot of the disciplines outlined in this book has it's source in Eastern religions. For example contemplative prayer and meditation. After reading this book, I can assure you there is no hint of Eastern mysticism. Everything Foster mentions has it's roots in early Christianity.
Overall, "Celebration of Discipline" is an excellent book. Perhaps the best in regards to the subject of spiritual disciplines. Full of great insight and practical experiences. Foster segments the book into three categories of disciplines: The Inward Disciplines, The Outward Disciplines, and The Corporate Disciplines. Within each of these categories there are four chapters, touching on everything from meditation, prayer, and solitude to service, confession, and worship. Each chapter involves a reading, questions, and Scripture readings relating to the topic addressed in the chapter.
I never knew there were so many disciplines. Nor, did I know there were many ways to pray, worship, and fast. Great insight drawn from the personal experiences of the author and the experiences of other Christians. I highly recommend this book to all who are seeking a closer relationship with God and who are seeking a better way to allow God to work through them.”
