The Sign of the Quatrefoil

As the title may suggest, the number 'four' is of prime importance in the book, and although the author does not follow a numerology based concept, it's certainly the essence driving the book's content. Paul enters into the theme of humanity's endless quest for a fifth element (The Holy Grail, The Philosopher's Stone, The Emerald Tablet), and that the reason we have not yet attained that level is because this quintessential 'fifth plane' can only be created or emerge when we first focus on bringing together the 'four' intrinsic parts of our being.
Paul's language is clear and concise. He explores the sensitive and burning topic of 'four' forming the foundation of patterns and phenomena, past, present and future, with a variety of examples from nature, science, time, esotericism, ancient culture and humanity. His message is that we are now at the stage where we must search for this fourth component. Like three triangles leaning in towards each other awaiting the 'fourth' piece to create a separate pyramid - our fourth part will complete the whole, and yield a fifth, separate entity; a Golden Age where we are all fully accomplished beings.
It teaches some basic practical exercises in the release of materialism, breathing, visualization and meditation. The objective is to determine in what way any set of four may be drawn together harmoniously to produce a new fifth unit, which is greater than the sum of its parts. It is often the case that when we identify a set of four elements, steps, objects, feelings, ideas, states or beliefs, we find that either we are missing one of them in our lives, or else we have failed to join the pieces together coherently.
