However the cover is almost the same, in Dutch this book is called “De Sleutel” (“The Key”). The writer was brought up a Kabbalist and mostly appreciated the teachings of Yehuda Ashlag (1885-1967). Berg gives a spiritual guide for everyday life in this little book. This may be based on the Kabbalah, but don’t expect to read about Sephiroth, anpins or Hebrew letters. Many stress is put on developing the ability to share, but you will get a quite whole spiritual worldview.
At the end of the book Berg proves to be the brother of the famous Kabbalist Yehuda (Philip) Berg of the Kabbalah Centre (kabbalah.com) of who Madonna (for example) is member.
All in all a nice little book that shows another side of the Kabbalah than the one you usually read about.
