Almost all of the physical books are gone and will not be reprinted and stored here, so when they are sold out, this product will be .pdf only.  Sunology has changed - the biggest change is in the graphics since the clock works clockwise vs. the counter-clockwise orientation that was used. These changes are currently only be made to the .pdf version, which has limited graphics. However, it offers the interpretations of the symbols. This book is a precursor to the new clock. It has full graphics, including drawing by Kimi Nyland and graphics by Mary Argodale.
