The hearing of a voice in the absence of a speaker is commonly regarded as a sign of mental illness, yet many ordinary people throughout the ages have had this experience. The voice is sometimes recognized as belonging to a relative or friend, who may be alive or dead, or it may be completely unknown. In this well-researched book, Rodney Davies examines numerous historical and present-day cases of this truly remarkable phenomenon. He not only reveals that disembodied voices are a generally positive influence in our lives, but he argues that their reality points to the existence of guardian spirits or divine beings who take a benign interest in our welfare.
