Sacred Geometry charts the unfolding of number in space and differs from mundane geometry in the sense that its moves, concepts and products are regarded as having symbolic value and meaning. Thus, like a good melody, the study and practice of geometry can facilitate the evolution of the soul. As we shall see, the basic journey is from the single point, into the line, out to the plane, through to the third dimension and beyond, eventually returning to the point again, watching what happens on the way. These pages cover the elements of two-dimensional geometry-- the unfolding of number on a flat surface. The three-dimensional geometrical story is told in another book in this series. The material is this book has been used for a very long time indeed as one introduction to metaphysics.
