A Kabbalist has two functions: one relative to the Creator and the other relative to the created beings. In many cases, they are interconnected and one affects the other, but they are still two different missions.
Relative to the Creator, a Kabbalist does a special type of work within the system to which he belongs. There, he is connected with the Kabbalists of all generations who reside in this system as corrected souls. He realizes his designation in the root of his soul, in the place where he belongs within the system. By revealing the Creator, he delights Him.
Relative to the created beings who haven’t yet come to individual attainment, to the best of his ability, he shares the knowledge of the wisdom of Kabbalah and helps them to approach the upper system, consciously enter it, and take part in correction.
To accomplish this, Kabbalists write books. A book is a revelation. Every generation needs new books since with every new incarnation souls become renewed. They are characterized by greater egoism and a new type of perception. Besides, even in our corporeal world, the conditions for the Creator’s revelation are changing as well.
Therefore, Kabbalists have to keep improving the method of Kabbalah. This is the very same method that was revealed by Adam, but in every generation, it has to match the collective desire. As the desire grows, the conditions between the Creator and us change, and this is what Kabbalists write about.
When we attempt to penetrate the depth of a Kabbalistic text, we see that it isn’t simply letters and words, but rather a mechanism that works on us as we speak. The text is a program that is put on a person to work with his desire so that it starts corresponding with the upper system. That’s when the person becomes a part of it.
Through the book, a Kabbalist passes on to the students how to build the intention, how to act and interconnect. Moreover, he passes along the internal force from the spiritual system. It enters the person while he is reading, but affects him only on the condition that he desires to change to be like the Kabbalist whose words he is reading and that he wishes to penetrate the text to reveal that which is being described.
