In both 1995 and 2007,

when we last gave percentages, we stated that 7% of incarnating souls on Earth were firmly in the Service-to-Self. This percentage has significantly dropped to 4.6% because the population aged and died, and no new incarnations from the Service-to-Self pool have been allowed to occur as a rule. These souls have moved on to the prison planets that await them. There are few exceptions. Another incarnation might be allowed only to someone on the cusp, so they can make their final determination.

In 1995

we stated that 25% of the incarnated souls on Earth were firmly in the Service-to-Other orientation, but by 2007 this had grown to 33%. The Earth’s population had grown from 5 billion in 1995 to 6.5 billion in 2007. All in the Service-to-Other orientation who died and were allowed to reincarnate on Earth. But most of the increase was due to the presence of Star Children,

who are either incarnating into newborns or stepping into the bodies of unsparked or undecided humans. At present the percentage of incarnating souls in the Service-to-Other orientation is 47%

For many reasons the population on Earth will change in percentage as a result of the Pole Shift. We and other alien groups communicating to mankind estimated that 90% of the world's population would die as a result of the Pole Shift. Most live on the coastline or in river bottoms where fishing and boat transport is handy. Even if warned, they will not move to safety. Denial is in sway. Those that have or will move to safety are courageous Service-to-Other individuals. Thus, the population after the Pole Shift will be almost exclusively in the Service-to-Other.

The Earth, at close to 5 billion people, is approximately 25% Service-to-Other orientation, 7% Service-to- Self orientation, and 68% undecided. These percentages move about a bit."

If there are a billion incarnated Star Children on Earth at present, why does it seem they are not making a difference? We mentioned that the Arab Spring was greatly assisted by Star Children, who acted as Walk-Ins, knowing the torture and death they would likely face. Jesus was an example of a Star Child determined to make a difference, courageous in the face of crucifixion. Is courage such a rare commodity among Star Children?

Of the 6.5 billion humans on the planet, only about a billion are incarnated with reincarnating souls. The remaining 5.5 or so billion are in a virgin incarnation, which may or may not result in a sparked soul. Of the billion or so reincarnating souls on Earth, approximately 33% are Service-to-Other, approximately 7% are Service-to-Self, with the remainder being undecided.
