The spirits or vibrations of nature are the instincts that keep the world functioning: the human, the animal, the plant and the material instincts or life forces. They can have a drastic affect on the human soul: why, for instance, do religions pass through a phase during which they seem to condone cruelty and violence? In mythological terms we have all descended from Eden to the very gates of Hades, and this book tells in practical terms how we can make the return journey, carrying the benefits of materiality with us.
