Written from a Wiccan perspective but inclusive of many paths and traditions, this guide to understanding the nature of discarnate beings is a multi-layered summation of over 20 years of esoteric experience, study and practice. The author examines the similarities and the differences between spirits, in effect comparing their ethereal anatomies, and presents a unified system for understanding non-physical beings. Dominguez includes a few exercises and techniques, but primarily discusses the mechanisms of spirit contact.
