This book describes the spirituality of L'Arche, an international movement founded by Jean Vanier in 1964 in France. The Heart of L'Arche was first published by Novalis in 1995 and has been in demand ever since. This updated edition was revised by Vanier himself, as he looks back on 47 years of the spirituality of L'Arche, at the age of 83. Readers will discover the spirit that keeps Vanier's dream alive and thriving in a world where people with disabilities are often ignored or seen as a burden on society. With simplicity and conviction, Jean Vanier shows how a life shared with people who have intellectual disabilities calls us to selflessness and risk. The vulnerability that is so much a part of their lives reveals our own limits and forces us to ask questions that can lead us to profound liberation.
