Each different "plane" or frequency band within the reality spectrum vibrates across a discrete range of frequencies. Each "form" that we occupy takes its characteristics from the frequency band it occupies. We have different bodies for each part of the spectrum of reality.

The bodies we are in right now are the appropriate vehicles for us at this level of reality, just as the caterpillar's body was uniquely adapted to its type of existence as a crawling insect. However, in order to inhabit Terra, we have to become "butterflies" — we have to transform into totally different kinds of bodies that will be the appropriate vehicles for that level of reality.

When the Messages say that we do not have to die, it is the same as the caterpillar-to-butterfly transformation: there is just a change in form, but the particular lifestream continues without interruption. Those of us who are destined to colonize Terra will not die; we will simply change form. In fact, we are already well on our way to doing just that.
