The worlds were created in such a way as to be able to rise above their intrinsic level. Indeed this was the very purpose for which they went down ever since their first descent at the time of the breaking of the vessels – in order to ascend little by little until everything returns to the level of completeness as before the breakage. And now there are ascents and descents depending on the different times, in order to govern the worlds with the necessary measure of increase and decrease as required in any given circumstances.
The Cosmos Operates on the Principle of Repair
