For you Houstoners, there is a building on S Shepherd called "The Kabbalah Center" that uses a map of the 10 sefirot as it's logo. It looks like something that might exist in other cities. All the books inside are written by one man, Yehuda Berg. Is this place a genuine place to study Kabbalah? Is this man an accepted Kabbalistic scholar? Can anyone explain who this man is and what these places are?
The phrase "at forty for discernment" (wisdom) is traditionally understood to mean that a person needs to both reach the age of forty, AND complete all of the previous prerequisites (mastering Scriptures, Mishnah, Talmud, getting married, having a career, etc) before one can properly understand Kabbalah. (See the Shach, Yoreh Deah 246:6)
The Kabbalah Center is a dangerous cult, that uses some authentic Kabbalistic ideas from Rav Ashlag, just enough to impress spiritual seekers. Then, they squeeze every last dollar out of their victims, promising blessings for giving, and curses for not giving.

Rather than give you my story, you can simply read these (fairly accurate, as I know first hand) and see for yourself.
