This is a book Renford says he never expected to write. Due to his long held view that the Book of Revelation was a negative and destructive book, he felt it had no place in the New Testament.
This view changed with the development of his understanding of the Universal Laws, the innate powers of man, and the significance of the symbols and numbers.
This book is a metaphysical interpretation of the Book of Revelation, which Renford shows as a roadmap to soul unfoldment. Though most consider it a book of riddles and external prophecy, its application is to the individual development from relative thought to higher thought. It is The Mysteries Revealed.
