There are many words to describe reality, but the ultimate reality is one. Whatever our religion or language, whatever word we use to describe God or the ultimate reality, that reality is the same.
In order to understand any religion or mysticism, one must understand the way energy and matter function throughout all the dimensions of the universe. This knowledge is represented in the metaphysics or mathematics of every religion, which all emerge from the same source.
Kabbalah is a Hebrew word that describes what is studied in every religion. The Hebrew word Kabbalah refers to the study of the fundamental laws that support all existence and non-existence.
Although Kabbalah is commonly believed to be exclusively Jewish, study reveals that every religion in the world teaches Kabbalah.
"One is filled with admiration, on penetrating into the Sanctuary of the Kabalah, at seeing a doctrine so logical, so simple, and at the same time so absolute. The necessary union of ideas and signs, the consecration of the most fundamental realities by the primitive characters; the Trinity of Words, Letters, and Numbers; a philosophy simple as the alphabet, profound and infinite as the Word; theorems more complete and luminous than those of Pythagoras; a theology summed up by counting on one's fingers; an Infinite which can be held in the hollow of an infant's hand; ten ciphers and twenty-two letters, a triangle, a square, and a circle,--these are all the elements of the Kabalah. These are the elementary principles of the written Word, reflection of that spoken Word that created the world!" - Albert Pike, quoting from Transcendental Magic by Eliphas Levi
"In order to pass to a superior Level of Being, it is necessary to cease being what one is. We need to not be what we are. If we continue being what we are, we will never pass to a superior Level of Being."
