To ensure movement for an expanding universe.
Each era has specific impulses with which being human is activated to create God/Creator. This is not a fixed plan, this is completely in accordance with the will of man who can and may create his own future with it. We are continually taken along in new impulses to grow along with the expanding universe. We must and may use our will to achieve this. Because this is still very difficult to understand and we tend to want to hold on to, for example, the Age of Pisces, the transition for humans is still in full swing. Humanity is struggling to keep up with the new impulses.
