There's another way to make the evolution possible. By binding souls and making earthly souls conscious. The binding of souls gives enormous powers that provide possibilities to make a new step in the human evolution.
2 (or more) souls can be bound by their identical
harmonisation degree without slowing down their growth. The souls are
"compatible" and there will emerge a "connection" . This connection is very
useful to help stationary souls. The power of this connection can even help
souls with higher harmonisation degrees.
This connection can also be used to become
"compatible" with souls that have a higher harmonisation degree. The connection
makes "contact" with higher evolved souls much easier because they're on the
same harmonisation degree.
When enough souls are
bound they can even reach a divine harmonisation degree. You could name this god's
arrival on earth.
