Torah, “Leviticus” (Acharei Mot), 18:9: The nakedness of thy sister, the daughter of thy father, or the daughter of thy mother, whether born at home, or born abroad, even their nakedness thou shalt not uncover.
This is about a system of mutual cooperation between the male and the female parts of the general vessel (Kli).
Every part of the vessel of receiving is of a female attribute. The male attribute is the attribute of bestowal that cannot connect with the female attribute (the desire to receive) if they both stem from incorrect connections between them.
Thus, the prohibition of “The nakedness of thy sister… thou shalt not uncover” refers to the fact that it is impossible for these two parts to connect when there is no Light of Hassadim in it. That is the clothing, the dressing on the Light of Hochma.
At least twenty attributes of each Light and their names are clarified in Talmud Eser Sefirot (The Study of the Ten Sefirot) since it is very difficult to explain. However, we must understand that we are in this world only in order to work on the correction of the soul.
Now, on the current level of our evolution, we have entered the system called this world, and we must exist in it for a while and perform certain actions, and then move on.
The Torah speaks only about the corrections that we must perform while being on the level of this world when we feel ourselves inside a body, by corporeal means. The Torah doesn’t speak about the rest of the huge round we must undergo and about the other parts of our path.
When we speak about this world or about our world, we refer to our current state, and to what we think and feel now. It is because our world is a certain condition. We are placed in a certain block that was shattered into time, place, motion, and so forth, and we must perform certain actions on ourselves while living in it.
