The Zohar is a Kabbalistic commentary on the Hebrew Bible. Long before the 'Bible Code,' Jewish scholars were attempting to wring deep meaning out of every syllable of the text of the Hebrew Bible, using numerology, gematria, and other techniques. Dozens of pages in this book are devoted to analyses of the hidden meaning behind first few letters of Genesis! This might seem ultra-pedantic; however, the Zohar makes the Biblical text come to life, brimming with mystical significance. Seemingly unimportant details and turns of phrase, which you may have read long ago and forgotten, lead to immense vistas of a mysterious world inside the world.
