Answer: The technical study of Kabbalah without its practical application does nothing. You will never be able to memorize anything. Even if you memorize some details, it will not help you in any way, it will not fill you, nor will it elevate you. Only spiritual work can elevate one upward.
We study the entire system of the Universe only so that we can attempt to understand it in some way and determine what is important for us. For us it is important to draw the upper Light, to become filled with the Light of Hassadim (Wisdom), and to rise from the worlds of BYA to the world of Atzilut. This can be done if we unite. As we unite, we rise to ZON of the world of Atzilut where we find ourselves under the influence of the reforming Light.
We need this system only for the purpose of convincing ourselves to do the necessary actions together. Then the correction will take place, and as a result, every one of us will see and sense himself inside of this whole system. He will see it for real and will be able to freely navigate within it. This system is the connection between us. However, if we don’t try to connect with one another, we will not reveal it because the worlds are something that exists between us.
In other words, when we aspire to one another in similarity of properties, in mutual guarantee, we reveal the worlds and the Light within the worlds. The general Light which becomes revealed is the Creator.
