Continuance (and probably some conclusion) on densities

[Bring4th_Austin]

apparently, ongoing generations will give birth to increasingly 4d oriented bodies.

Perhaps I'm being overly stubborn in understanding this. I get the idea that each generation will have a more 4D oriented body...but this just leads to more questions. This means there WILL be a dual body generation give birth to a completely 4D generation. Am I alone in seeing how this may cause problems?

Also, since Ra said the transitional bodies are designed to allow us to appreciate 4D vibrations in a 3D reality without interrupting the 3D body function, how will such rapid evolution not effect our 3D bodies? We can't just have a generation born, half electric body, half chemical body...our current chemical body is too intricate to be interrupted abruptly like that, even given the max of 700 years transition.
