everything that is going on is multi facetted. the things that are happening in the world is the same as what is going on outside the world. the things that are happening within certain people are the same as what is happening in what you are calling the astral.
its not just stuff leaking through into there , it is change. even though thats how it appears it is all cyclical.
something has to be the destroyer. it is just how it works. we can call it demonic and bad as that is how it all appears.
there is change going on. for that to happen. absolute chaos must reign for a while.
