Infinite number of octaves

It must be considered that Source is evolving, too. It follows that as we evolve and add to the all, Source—the all—evolves.

So if Source is evolving, there would be no end point.

I don't think the Source evolves, the Source is infinite. Evolution seems more like a process of finite things reaching infinity by living close to infinity. I view the source as a comon higher self to all our higher selves.
