In A World Transfigured: The Mystical Journey, Philip Sheldrake demonstrates the importance of the mystical dimension of religious belief and practice. Using the words of the great theologian, Karl Rahner, Sheldrake makes the case that the Christian of the future will be either a mystic or nothing at all. In our contemporary world, this judgment applies equally to other religions as well.

After chapters on the meaning of "mysticism" and the connection between mysticism and beliefs, Sheldrake describes important dimensions of mystical writings, illustrated by a range of examples. These are "Love and Desire," "Knowing and Unknowing," "Wonder and Beauty," "Mysticism and Everyday Practice," and "The Mystic as Radical Prophet." Finally, the book briefly explores why mysticism fascinates so many people in our modern times.
