The Kingdom of the Gods is based on knowledge revealed in occult books like The Secret Doctrine of H. P. Blavatsky and clairvoyant investigations by occultists like Annie Besant, C. W. Leadbeater and the author himself. As to the proof of the existence of these invisible beings the author points out that, while there can be no demonstrable proof of the fruits of mystical experience, test by personal research is possible and he says, ‘That test I have attempted to apply, and this book is in part a record of my own findings’.

Geoffrey Hodson (1886-1983), was an occultist, Theosophist, mystic, Liberal Catholic priest, philosopher and esotericist, and a leading light for over 70 years in the Theosophical Society.
