The Unification Epicenter of True Lightworkers
The problem with the Zeta is that you never know which faction to believe. They can all be very convincing.
In the end, they all have their own agenda, except for the faction that is genuinely trying to save their own race. Their biggest problem is that they indeed need us to unlock the secrets of the light body, because they have fallen so far that they cannot activate their own. This is the point of their observation and experimentation.
I can see why they are trying to spread the news far and wide, because when that wave arrives, they will have to phase out of this reality back to their own and wait for it to pass. They do not move 'up', they move sideways. Once that wave has passed, it will be another 20 thousand years or so before they can try to cajole another species into giving them the secrets they so desperately need.
They cannot join us where we are about to go, and that is something truly tragic, but some of them are doing their best to stop us from going anywhere. My advice when dealing with the Zeta: be very cautious.
P.S.: This information was given to me in a dream several weeks ago, while I was trying to contact the Arcturans. I have no reason to doubt its validity.
