Kabbalah means the “secret” or “hidden tradition”. Some Kabbalists had deep visions about the creation and workings of the Universe and described in a variety of esoteric ways. One of the ways of describing the visions was the Tree of Life formation, and is the most common representation of these concepts. Thus Kabbalah became both a way of viewing creation and a way of life for many Jewish mystics. The vision of the Kabbalah says that reality is created by sound, light and color frequencies.
