At Maurice Cotterell's request, this book is now permanently out-of-print. It has in any case been superceded by Adrian Gilbert's more recent work: The End of Time (American edition titled 2012: Mayan year of Destiny)

Adrian Gilbert is the author or co-author of a number of best selling books, including The Orion Mystery, The Mayan Prophecies, Magi, Signs in the Sky and The End of Time.
For nearly forty years he has been following the path of gnosis, i.e. knowledge of the truth concerning the universe and man’s possibilities within it. This has taken him all over the world, exploring diverse cultures and philosophies.
Though his published work mainly concerns new approaches towards the understanding of ancient mysteries, his interests are much wider in scope than this. They include Christian mysticism, yoga, astronomy, astrology, physics, alchemy, sacred geometry, Gurdjieff/Ouspensky, psychology, tarot, prophecy, Mayanology, Egyptology, pyramids, Zoroastrianism, hermeticism, spiritualism, kabbalah and the quest for the Holy Grail.
Based on the evidence of the long-term movement of the stars, he believes that the world is currently going through its most major change for at least thirteen thousand years (and probably much longer). This change embraces much more than an alteration of climate: it has profound consequences for us all. We are moving into a period of history that offers new opportunities for self-transformation, both as individuals and as a species.
To this end he has set up this website. While it is a show-case of his published work, it is also intended to be an oasis for those seeking a reliable philosophy that brings together the wisdom of the past with the science of the present. It is hoped that it will in time develop into something more than this: an on-line school for those who wish to follow his path towards enlightenment.
That should give you something to work off of
