The Kabbalah is essentially made up of three key books:
- The Zohar [made up of (I think) 22 volumes in Hebrew, of which there are 5 volumes translated into English]
- The Bahir Illumination
- Sefer Yetzirah: The Book of Creation
I recommend Rabbi Aryeh Kaplans revision and translations for the last two books mentioned in that list above.
I use the spelling Kabbalah which denotes Jewish mysticism. However, there are other spellings of the same word, each denoting their interpretation or association. For example, you might also see the word spelled as Qabalah, which is the spelling used when it is linked with its Egyptian roots and also among occultists such as Israel Regardie and Dion Fortune, to name a couple.
The Kabbalah is NOT a religion; it is a path or an understanding, a way to interpret the world around and it has a goal of unity with the divine force (i.e. the Supernal Union).
Among the Jews and branches and sects within Judaism, the Kabbalah is often discouraged and even
verbally forbidden by the rabbis. The only branch or sect of Judaism that I know of that openly teaches the Kabbalah and reads passages from
The Zohar in their services to all congregants are the Chassidic Jewish sect of the Orthodoxy branch.
Many Jews and rabbis often associate the Kabbalah with witchcraft, magic and things of the occult nature. They are not incorrect in saying that. The Kabbalah does technically teach occult knowledge. Occult here meaning hidden knowledge. However, over time, the word occult has taken on a negative connotation, having been demonized and the followers persecuted especially in Western culture, especially by the rise in power of the Roman Catholic Church. Therefore, nowadays, many people shrivel at the word occult, thinking it means something evil. Many of the rabbis, for whatever reason(s), were influenced by this message and currently attempt to dissuade their congregations from studying the Kabbalah.
In Judaism, the rabbis often teach that a person must meet the following requirements in order to be worthy of studying the Kabbalah: 1) must be male; 2) must be married; 3) must be at least 40 years old; and 4) must have studied Torah all their life. If that sounds a bit ridiculous to you, then it is as it should be. Those requirements, though not written, but orally communicated, are attempts merely to dissuade; however there is no official ban on the Kabbalah within Judaism (to my knowledge).
As I stated before, your question is very broad. You asked if I could define the core beliefs of the Kabbalah. I will attempt to define a few, which I will discuss in further detail as this thread continues. It is my hope that this discussion will spark questions in your mind and others as we continue. I am happy to speak about such things; however, it is difficult, at times, because the occult knowledge has been so well-misplaced, intentionally, over the centuries, in order to keep the masses from the understanding of their interactive worlds and to also keep people from gaining access to the kingdom of heaven that is inside you, as even Jesus taught.
The Zohar is the primary book of the Kabbalistic teachings. And within Judaism, both the
Talmud and the Chassidic commentary
The Tanya can be used as additional reading materials.
The Zohar is a quite interesting read, but it can be very difficult to comprehend for those who lack the unique perspective of Hellenistic culture.
The Zohar is a long dialogue between Jewish sages/rabbis who speak in both a direct and indirect manner concerning the greatest mysteries that had been passed down in mystical sects for hundreds, even thousands of years prior to their being written down, in order to preserve the knowledge when they were facing the real possibility of being killed for their beliefs after the rise of Christianity.
Some of the topics covered in the 5 English-translated volumes of
The Zohar are listed here:

As you can see from the link given, it is quite extensive, and explains all sorts of things, such as the mystical meanings for the dimensions and structure of the temple and the subsequent magical purposes of animal sacrifices. It goes in-depth about the creation of man, especially with consideration to mans divinity. And nearly from cover to cover, it beautifully expresses the Supernal Union (Intercourse) with the Shekhinah. Jewish mysticism concentrates heavily on the union of right and left, heaven and earth, male and female, spirit and man, equal and non-equal, good and evil and so forth.
Though I am strongly acquainted with Jewish mysticism, I do believe as Israeli Regardi and other scholars have taught: The Kabbalah predates Judaism, and its roots are in Egypt, as it is said that Moses brought the Kabbalistic teachings from Egypt, after he (Moses) was most assuredly taught by the magical practices. Therefore, I also ascribe to a broader understanding of the Kabbalah to include more modern terms such as Sexual Alchemy, which is a term used much later on in history. Similar teachings to the Kabbalah and are often used when studying
Qabalistic teachings, include, but are not limited to: Gnosticism, Hermeticism, Greek mythology (to a degree), Egyptian beliefs and so on.
I realize that all this is a lot of stuff to throw on you at one time initially. So, I encourage you to mull over these things and scan, if you will, this page too, which is not complete, however it describes Sexual Alchemy in the Kabbalah quite well.
