In the book "Ghosts Around Us" James Hollis talks about how people respond to manifestations of such invisible forms as the shadows of parents and distant ancestors, inner voices, fantasies, impulses, untold stories, complexes, synchronicities and sacraments that move through us and through time. He shows the way to their psychological understanding, studying the influence of the past on our present conscious life, and emphasizes the need to immerse ourselves in this mysterious world. Such immersion can make our lives more profound, more meaningful, more interesting.
