EXCERPTS
The only way to get from this level 5 existence to the level 3 density of the planet requires what Josh calls an organized energy matrix conversion. We are, I guess, an organized energy matrix, both here and there, so what they have to do is take that matrix and add to it a bazillion times the amount of energy to convert it to level three. This is only possible with living tissue, so when you get converted you find yourself on the planet completely naked. So part of the training here was done in the nude. The girls called it naked training.
