Kabbalah is known as the oral tradition even though it is said to be recorded now. Some say this goes back to Moses, some say the oral tradition goes back to Abraham and some say this goes back to Adam. The hasidic seem to be the keepers of that tradition right now. They have some of their teaching on YouTube. I have been learning the hebrew language from them. The letters actually have a symbolic meaning. WE can understand the meaning of a word by doing a study on the letters that make up that word. For example if you were to study the word "beginning" in the Bible we see that the Son of God (Ben) was given as a grain offering so that Heaven and Earth could be united. As it is Heaven and Earth are divided. The word and is actually the more important word in this sentence. It is interesting to understand and study the Ancient Hebrew they used back before the tower of Babel when the language was confused.
As interesting as the Hebrew language and roots of our faith are to me-
I would advise caution. Pray and use discernment with Kabbalah. It is bound up with Jewish mysticism.
These are very much traditions of men. If Kabbalah really lead to truth they would have found Yeshua by now.
It is possible in this world to educate yourself stupid. (so to speak )
