Maybe this is a silly idea.... But since the "war" is spiritual in nature... Would it be sensible to apply some basic occult philosophy?
The people on this forum for what I have seen are quite strong minded and so far I've seen intelligent and powerful people. Many with mystic experience. In short co creator material.
So how about just choosing the outcome? Creating it. It won't even take a lot of energy. The so called dark side is fewer in numbers than the souls on this forum. The difference between us an them is organization. They had hundreds if not thousands of years to organize. And what you're seeing out there is the effect of the momentum of plans that started many years ago.
However as we approach 4th density more and more people come in contact with their true higher selves. They will begin to realize the error in their way and just change sides. It's clear we will accept all those that stand with us with compassion and joy. The whole apparatus begins to fall apart and momentum ends up to be the only thing left. This is already happening. They're behind schedule getting a lot of bad luck and more and more allies step away from them. I've been suspecting they're already being opposed for a while. They're really not having a good time at the moment.
I'm not a big fan of a meditation or prayer or something like it, although they can be strong they're ritualized and can be done habitually without emotional investment we need something more akin to an agreement, a decision of the council of free men. Something those of a non spiritual nature can agree with as well.
Perhaps something as simple as a glyph, a doodle that can be drawn that stands as a reminder of the agreement and can be used as a symbol of recognition. Or in another way a topic that states the agreement and that asks people to sign with their message and maybe a one liner. Perhaps even both

The whole thing should be broadly phrased with as little complication as possible so there can be no differences in interpretation. It should be clear what it does and do so in just a few words or sentences. And it should support the values of light. So no death wishes, violence, stomach cramps or crap like that.
A clear synchronized statement of intent from a whole lot of creators causes magical effects. Also it empathizes our oneness.
The whole idea would be crazy... But after all... It's a spiritual war. It requires in part a spiritual approach! And we've got the soul to do it.
If the idea resonates with enough people then perhaps we should discuss how we'd go about doing it? I suggest developing the text or glyph in an open thread allowing everybody to review it and comment on it. And then a new thread for the signing.
Does anyone have ideas or input in the matter?
