We must build from our desire for pleasure such a form that the Creator can clothe and be revealed in it and we understand who the Creator is, what He wants from us, and how we can be connected to Him, how to rise from our level of creation, from the level of dust to the level similar to the Creator.
To do this, we need to know how to build our Kli out of the material of the desire by means of contraction, screen, and reflected light.
The Sukkah symbolizes the corrected Kli. It is a building that serves as a model for our inner spiritual vessel. Therefore, there is a custom on the holiday of Sukkot to build a structure not inside our heart or in the union of hearts, but to build a Sukkah in an external form as the symbol of a corrected heart, a corrected soul.
The Sukkah is built from the simplest natural material. For its construction you cannot use iron or concrete but only wood, stones, branches, or leaves—anything the earth gives. This is how we build our corrected Kli, the soul, in the form of a hut, a Sukkah, like in child’s play, we build the desired spiritual state in material form.
Based on the details of the construction of the Sukkah described by the Kabbalists, we can understand what a soul is, what it is made of; and what states it passes through. Baal HaSulam and Rabash were very sensitive to this holiday and took care of building a good, beautiful Sukkah because it identifies a person’s attitude to the correction of his soul.
Sukkot symbolizes that we have reached the corrected Kli in which there are four stages, the four walls of the Sukkah. And the Masach for the desire to enjoy called Schach is the roof of the Sukkah. And we are inside the Sukkah, inside the soul, and nothing remains outside because we have corrected the whole soul and unite within it with the Creator.
During the seven days of Sukkot, we invite guests, the seven Sefirot to the Sukkah. Keter, Hochma, and Bina are above the roof of the Sukkah, and the Sefirot Hesed, Gevura, Tifferet, Netzach, Hod, Yesod, and Malchut are under the roof. This is how we celebrate the entry of the light from the degree of GAR to VAK into the body of the soul.
