The first part of the book, written in a single, uninterrupted flow of inspiration, takes the form of answers from the word of nature to questions posed by the rational mind. The second part of the book consists of philosophical reflections on the first and proposes the practice of imagination as a way of evolutionary development. Many traditions have spoken of a higher consciousness, but Schwaller de Lubicz’s attempt to formulate in modern terms an alchemical science of qualities, functions, analogies and signatures is unique.
