Question: Why did the world of Atzilut not break along with the world of Nekudim? Does it have a defensive mechanism that prevents breaking?
Answer: That is right! This mechanism is called “the correction of the three lines,” when the raising of MAN, prayer, and the connection between the receiving and the bestowing part is realized directly, unlike in the world of Nekudim, where all the Light descends into the Kli, desire, and leads to the breaking.
In the world of Atzilut, the Kli first prepares itself by lining up the three lines. It is as if it has gotten in touch with the Upper One ahead of time, and knew ahead of time what it was going to receive.
It knows the entire complete Light that the Upper One can give, the entire level (GAR), but it decreases itself to a certain degree in order to only receive a part of that Light, and it only accepts it in the bestowing Kelim, Malchut, which has ascended to Bina, above Malchut itself. In this way the Light is revealed and accepted by the lower one.
In other worlds, unlike the world of Nekudim, the world of Atzilut has a defensive mechanism on both sides: 1. The Upper One, who gives to the lower one, only frees VAK de Hochma, only a small portion of Light; 2. As the lower one prepares to receive this Light, he initially contacts the Upper One and he himself forms a system called the “three lines” to be prepared to receive even a part of the Light, not directly but through the three lines.
