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.
