Kabbalah, or The Kabbalah, is a branch of ontological metaphysics (the philosophical examination and contemplation of reality and being) derived from the early roots of the Judeo-Christian tradition. The Kabbalah is not a religion in and of itself but rather a methodology and esoteric discipline that is primarily concerned with discerning the connection between the finite and the infinite realms of being as well as disentangling their hidden meanings and mysteries. Like most other esoteric traditions, Kabbalic teachings seek to explain the nature of man, the universe and their relationship.
The foundation of most Kabbalistic thought comes from collection of test works known as the Zohar, which means, “Radiance.” The Zohar focuses on three main topics, mystic psychology and inner knowing, a investigation of the esoteric messages contained within the Torah and lastly, a deep reverie on the origins of the universe via cosmogony models. The Zohar was originally written in a old version of Aramaic, thankfully, however, the book has been translated into numerous languages for readers to peruse the world over.
One of the foremost institutes for the study of Kabbalistic thought is the Kabbalah Centre International, a religious non profit organization based out of Los Angeles, California. The Kabbalah Centre International provides a extensive list of courses revolving around the intensive study of the Zohar and other associated texts. Most of the information is disseminated via study groups which can be attended by wisdom seekers the world over, either through the institutes brick and mortar gathering points or through the internet. All of the courses, along with the Centre International itself, was designed and organized by the American rabbi, Philip Berg alongside his wife, Karen Berg. For those interested in learning more about the teachings of the Zohar, the Kabbalah Centre Internal is a excellent resource.
