The wisdom of Kabbalah consists of two parts: the concealed and the revealed.
“Concealed” means forbidden to reveal. And what is the point in revealing? Indeed, everything can be written in books, but what a person can get from them depends on the state he is in. Thus one of the parts of the wisdom of Kabbalah is called “concealed,” because it is revealed only after certain conditions are fulfilled as a person goes through the cleansing of his ego.
It is also called that way since the upper part of the world of Atzilut is inaccessible to us. Even if I learn about the smallest, initial level of the spiritual ascent and am still in the worlds of Assiya, Yetzira, Beria and only later enter the world of Atzilut, still, even the smallest level I am on, the first ten parts called “one level” (one level is made of ten Sefirot), already gives me an idea about all of creation, but in a minimal way, on a small scale. Then I rise and see, like on a map that I read on a larger scale, everything there is enlarged.
But being at the bottom, I cannot bring the concealed part, GAR of Atzilut, its upper part, close to me in any way, which means to depict it. I can imagine different lower levels more or less, and then too I am always wrong, since every upper level is a new attribute regarding a lower level. Still, I can somehow imagine it, but not the levels that are concealed or that are called secret. All the levels below them are called revealed and we can reach them all, anticipating in advance what revelations they will bring us.
The first Partzuf of the world of Atzilut is called Atik, from the Hebrew word “ne’etak” – “cut,” detached and cut off, from our attainment. The next Partzuf is called Zeir Anpin, and the upper part of its “head” is called Keter, or more accurately Kitra (in Aramaic), and this part is also concealed.
Everything that is below this part is gradually revealed to us: Kruma of Avira, Mocha of Avira, Mocha Stima. The structure of all these parts is very interesting, since it is from them, from the revealed part of the head of Arich Anpin, that the Providence descends into our world, that our fate descends.
