The entire progress is realized only in the group of ten. From that moment on, we only work in it. The group of ten could be hundreds of our friends around the world. This also is called ten people, not nine or eleven.
Everything has the same structure of the ten Sefirot. The only difference is the scale, a greater or lesser resolution. You see ten people before you, but when you approach, each of the ten people turns into ten, and then each of these ten turns into other ten, and thus to infinity.
However, in essence, you see the same HaVaYaH, the same group of ten in which absolutely everything is included.
