Dangerous trails

Are there good and evil spiritual forces? What is the "cup game"? Is it possible to make a pact with these forces? How does sleep work? If we die, why do we have to live? What happens to the soul after death? Is there a paradise and a hell? Will this world exist forever or will it have an end? What is the aura? The aim of this book is to answer these and other questions, bringing together traditional sources to express the Torah's perspective on these matters.
