There seems to be a pull for people to study Kabbalah, as a system of discovery and evolution. It is one of many, and will remain popular especially as it is often a social experience. There are Kabbalah Centers in different parts of the world, not all teaching the same philosophies, but spiritual non-the-less. Often the journey creates new friendships with those of like mind.
Once again, it is all about healing ----> balancing ----> conscious awakening.
