It has been my high privilege to have some practical experience as the earthly wife of an angel from the unseen world. In the interests of psychical research, I have tried to explore this pathway of communication with the spiritual universe, and, so far as lay in my power, to make a sort of rough guide-book of the route. For not all wives of heavenly bridegrooms travel the same path at first. There are roads running into this one from every religion and folklore under the sun, since the pathway of marital relations on the Borderland was once, and still is, as I hope to show, one of the main thoroughfares connecting our world with the world beyond the grave. This thoroughfare, along part of which I hope to conduct the reader in imagination, is marked with signposts, many crumbling under the religious storms of centuries, others preserved as sacred trellises upon which to train a rank growth of flourishing superstition, and still others fresh with modern paint and gilding. Part of this thoroughfare runs straight through the Christian Church, or, to speak more accurately, the foundations of the Church are laid upon this very principle. For Jesus himself is said to be the child of a union between an earthly woman and a heavenly bridegroom who (however godlike, and whatever the details of the relation) certainly seems to have manifested to Mary on the occult plane.
