He doesn't speak in those terms, but from what I have seen, it is more of an energy transference, which begins a new cycle for the Earth and humanity, for all the cosmos, actually. It is a transformation. You can think of it as a merging into another dimension if that is helpful to you, but these are just words used to describe an indescribable, incomprehensible event or series of events, which will take place, during which everything that you know will fall away and an entirely new set of rules and relationship with reality will set in. Prepare for it, instead of trying to understand it ahead of time. For the wise, there is nothing to fear. He understands it perfectly, and has no concern whatsoever.
