This small book by Sufi teacher Llewellyn Vaughan-Lee Ph.D. is perhaps the most elegantly written book on the subject of the mystic's quest for communion with the Beloved ie. God, Goddess, Great Spirit, etc. As you read this small book seeds of understanding will be planted in your mind and as you think on the concepts presented those seeds will germinate into personal realizations regarding your own relationship with the Divine.
Though written by a Sufi, the ideas presented here are non-sectarian and highly valuable to any on the path of the mystic.
