The spirits or vibrations of nature are the instincts or life forces that give life to every creature on the planet. There are human, animal and plant instincts, and overall, giving them substance, the life forces of materiality, the 'instincts' that compel atoms to combine in certain ways and keep the universe functioning. At the outset, people were purely 'human': comparatively helpless, naked creatures who lived in the world of instinct. All the wealth and technology of the world is to be found within the material zone: and this broad field of material instincts - the home of civilisation - proved an irresistible attraction for humankind. As they acquired the skill to make and use artefacts, the material life forces (which already governed their bodies) gradually took over their souls too. An instinctive awareness of this spiritual descent gave rise to the stories of mythology which have been handed down to us. In mythological terms we have all trodden a downhill route from Eden to the gates of Hades itself, and the time has come to seek the path that will take us back to the very gates of heaven. This book tells how it can be done.
