The way the non-material embraces us.

Universes form in pairs.
So is ours.
The non-material side can see us.
We cant see them.
The difference is the concept of time.

On the non-material side they have perfect knowledge,
but no opportunity to act upon it because of the lack of time.
On the material side we have imperfect knowledge but complete power to take action.

So, the non-material side can only perform a minor act or communicate a single image.
Like clues.
Only if you pay attention you will see it.

Hence, creating a crop circle in a matter of seconds.
