The world of Atzilut expands the vessels. If at first I only had a small discernment. a point, one Sefira, then in the world of Atzilut a whole Partzuf of ten Sefirot is created instead of the one Sefira. This means that we can already separate all the attributes much more than before.
If before I could hardly see the difference between two attributes, since there was one point, now the whole point grows ten times larger and it includes different discernments that are interconnected.
So the world of Atzilut allows me to clarify things and to perform corrections of the world of Nikudim. In the world of Nikudim there are only points—a black point of Malchut that was incorporated in all the Sefirot. Here, however, in the world of Atzilut we don’t work with the same Malchut that is simply incorporated in all the other Sefirot as a black point, but with Malchut that includes the first nine Sefirot and is also included in them.
Thus the common attributes of the first nine Sefirot are created with regard to Malchut, and we can see these on the background of those. Thanks to that, we are able to choose, to clarify, and to understand what is going on.
It is like getting closer to an object, which at first I see as a point. The closer I get, the more I begin to see in a fuller scale what goes on there. Thus a small point on the map can grow into a whole city.
This is exactly how the world of Atzilut operates by helping us see every phenomenon on a large scale.
