Answer: There is no difference between a small ten and all of humanity. If we awaken a higher power through our actions in the ten, then through it we influence the whole world. Such is the peculiarity of the integral system that even a ten contains all parts of reality within itself.
If we pump the ten with higher light, then it expands and so does the size of all of humanity. Imagine that there are a billion people in each friend. There are eight billion people in the world and all of them, except the point of the Creator (Keter) and the point of Malchut, are within this ten.
As we move forward, we begin to reveal all of reality within this ten, all of humanity, all the worlds, everything is inside it, you just have to penetrate deeper into it.
