Rav Berg and his wife Karen are among a number of Kabbalah teachers who have managed to the Kabbalah to the public. Rav Berg and other Kabbalah teachers (in the Kabbalah Centre and elsewhere) explain that the 72 names of God have tremendous powers. These names appear in the Kabbalah among other sources. Reading or scanning them with your eyes can have great effects, is what they say. The Kabbalah Centre uses these 72 names in many of their activities, and they are also often quoted in lectures.
