Most kabbalah books can be complex. This one is great. I have recommended this book to over 75 people everyone who read it, loved it and uses the teaching everyday in their life.

The Berg dynasty has Kabbalah books filling the shelves of every major book store's Judaica section. They claim to have ties to the Baal HaSulum, Rav Yehuda Ashlag. While it's true that Philip Berg spent a brief time studying with a disciple of Ashlag's, even married (briefly) his daughter, this disciple was not the Kabbalist to whom the wisdom of Kabbalah was passed. Rather it was to Rav Baruch Ashlag (Baal HaSulam's eldest son) that the writings (Shamati articles) were passed. Rav Baruch Ashlag passed the wisdom on to Rav Michael Laitman, the Kabbalist teacher of the Bnei Baruch World Academy of Kabbalah in Israel.[...]
The Power of Kabbalah and the Berg books in general are watered down Kabbalah promising personal empowerment in this world. That is not what the wisdom of Kabbalah is about.

Caveat Emptor.
