Book of the Book 

Used for more than seven hundred years as a teaching story, The Book of the Book is one of the most compelling and astonishing texts ever to emerge from the Orient. Its central premise is the simple phrase: ’When you realise the difference between the container and the content, you will have knowledge.’ When the book first appeared in English thirty-five years ago, its printers questioned how it could be a book, as did reviewers, scholars, and people who paid money to buy it.The Book of the Book is now in its seventh impression, and is studied at university level, appreciated by all for its simple brilliance.
