As we delve further and further into our connection with each other and with All That Is, it's more and more important that you've read the previous posts that brought us to this point. If you jump in at this point without understanding the building blocks used to get here, it will probably be difficult to grasp the concepts thoroughly.
The last post began expanding on the concept that we collectively create and design our world. If you are a creationist and want to compare this to the biblical account of creation, try breaking it down into the following simple elements.
All That Is created the world; and
Each of us is a component or part of All That Is; so
We created the world.
Again, in order to accept this concept, we have to accept our own responsibility for the world and what happens to it. Just as we are responsible for the events that happen to us in our individual incarnations, we must also accept that we are responsible for what happens to the world at large as well. This now begs the question, why would we subject ourselves to all of the catastrophic events that occur? Why are there floods, tsunamis, droughts, tornadoes, avalanches, earthquakes and all of the other nice curveballs that "Mother Nature" throws at us? Don't we have enough to contend with already?
Actually, there are as many reasons for these 'natural' events that we create subconsciously as there are for the 'human' events such as war or environmental disasters that are created by us consciously. A 'natural' disaster is often a way for one incarnational group to force help from other incarnational groups. Remember that we're all here to learn something. In order for all of our incarnational experiences to be realized, we all have to assume one role or another. Some will choose to be 'victims', while others will choose to be 'rescuers'. So let's hypothosize that the 'victims' are living in abject poverty, and the 'rescuers', for whatever reason, are not responding to that need. The occurance of a 'natural' disaster will very often act as a catalyst to mobilize the 'rescuers' into action by drawing their full attention to the plight of the 'victims'.
This example has been over-simplified in order to get to its most basic structure and components. It's not intended to be an example of any particular or specific event that has happened, but as an outline of why the creation of a natural disaster can actually be beneficial and even desirable to a set of incarnational groups.
