The spirit world is the mental world and this universe is the mental construct of all living things. It's hard to wrap ones mind around it, so I am doing the best I can to explain it all in my book called THE TRUTH!
There are many parallel worlds to this one we live in and each of them are created through the vibratory resonance of our collective mind which is not in it's highest state of being, so we need to ascend our mind above the pressures of life. Otherwise our world will continue to become a powerful echo chamber of negative thought creating future nightmare which will remove all beauty. Our world is a paradox within a paradox and time is the recycling of events over and over again like a 7000 year groundhog day until enough people wake up and stop this cycle.
