When we speak of people dying, we mean the process in which the spirit separates from the body, leaving it behind to decay into its more elemental components, while the spirit moves on to occupy another plane of reality.

We have all done this so many times that it is easy to forget that it is not always necessary to do this when it is time to move on to another phase of our existence. Just as the caterpillar has not "died" (i.e. left its body behind) in order to become a butterfly, we do not have to die (i.e. leave our bodies behind) in order to become our "new selves" for the new Earth, Terra. We simply have to change form.
