Nothing in this universe is by chance. All that is taking place throughout the vastness of Universal Presence is interconnected in the most precise way to every soul on the physical earth plane. The life that everyone is leading is intertwined with this vast Universal Process within the Consciousness of God.
The incarnating of souls into various planes, dimensions, or physically perceived planets is part of the Universal Process, for the smallest particles of existence are as important to the functioning of Universal Life as is the Whole of Universal Life itself.
Again, nothing is by chance. The dimension and planet that a soul incarnates into-the parent souls that the soul physically incarnates through-are all by Divine Design. All souls incarnate precisely where they are supposed to-and through the vehicles of the physical parent souls that they are supposed to-whether seemingly to the advantage or disadvantage of the incarnating soul.
