Spiritual life is a process of inner transformation in which the whole psychic structure of the seeker is changed. Exploring the threshold between spirituality and psychology, Llewellyn Vaughan-Lee shows how dreamwork guides us on this inner journey and helps us to understand the different stages of the path. From the transformative darkness of the shadow he takes us into the love affair with our inner partner, and from there into the archetypal realm and the symbolic dimension of the Self. He explores the psychological dynamics of the relationship with the teacher, so often misunderstood in the West, and then describes what is hardly mentioned in the great spiritual literature of the world: how the soul of the disciple merges with the soul of the teacher. Catching the Thread is a pioneering work integrating the traditional wisdom of the Sufis with the insights of Jungian psychology–a valuable guide for any spiritual student.
