This book invites the reader to a spiritual odyssey。 It opens before the reader an itinerary for venturing forth with God， aided by the astonishing writings of seventh-century Isaac the Syrian。 Long-lost manuscripts have recently been discovered， translated， and published in scholarly works; this book aims to make them accessible to readers who want to experience their wisdom personally and so progress in a spiritual adventure。 Isaac’s writings are explored through the lens of his beloved metaphor of diving for pearls， which opens many avenues for reflection and spiritual practice。

This is a book to inspire preachers and teachers on prayer。 It will stimulate and offer a resource to spiritual directors and retreat givers， and it provides material ideally suited to quiet days and retreats。 A practical resource， it includes questions for individual or group reflection at the end of every chapter and a range of prayer exercises。 Above all， it is offered to those who want to leave the shallows and launch out into the deep in their spiritual journey。
