The Secret Doctrine Illuminated
Central to an understanding of kabbalah is the tree of life glyph, which is a basic map of the universal mind of which we are all sparks. Learn about kabbalah and its universal application, not only to every religion, but also to science, psychology and every ideology.
This is not a book that promotes mysticism. Far from it: the purpose of this book is to demystify that which has been held as arcane for thousands of years. The tree of life opens a window onto the human soul that some may find uncomfortable.
