I scaned it, it was great. I have not realy got into it yet.
I have sat several meditation retreats with the author, so I came to this book having already encountered many of these techniques and ideas in a practical setting. While there is no substitute for person-to-person instruction, you can get pretty close with this book/CD.
A warning: if you are looking for the sort of pseudo-Kabbalah being peddled by Rav Berg and the Kabbalah Center, this book is not for you. There is no bottled water here, no red threads or other magical nonsense, nothing to appeal to the Madonna-wannabes. Real Kabbalah is invisible on the outside. There are no fashion statements or other ready-to-wear "spiritual materialist" baloney.
Real Kabbalah is all about quieting down the constant internal monologue so that we can learn to see the Divine in all Its manifestations. Once you get tired of the pop-culture distortions so prevalent today, take off that silly red thread, dump the bottled water onto the begonias, and crack this book. Sit on a chair (or a zafu if you prefer), and try these meditations. You'll gain more self-awareness and God-awareness from one hour of clear mindedness than from a hundred thousand miles of red string.
