This French-language work presents the life and teachings of Lama Namgyal, a Western Buddhist monk associated with Tibetan Buddhist practice. Combining personal narrative with spiritual instruction, the book traces his path into monastic life and reflects on the disciplines, commitments, and insights shaped by Buddhist study and retreat. It offers readers an account of religious vocation from a Western perspective while also introducing themes central to Buddhist practice, including meditation, ethical conduct, and the guidance of teachers. The result is both a biographical portrait and a contemplative introduction to the author's spiritual formation.
