Answer: The only vessels, desires, that can receive the Torah are Galgalta ve Eynaim (GE). But it is possible to move forward only with vessels of AHP. Therefore, we advance only by the combination of GE and AHP, and all the preparation is done by the mutual incorporation of the two: Israel in exile with the nations of the world.
Question: Does that mean that only the vessels of GE need to attain mutual guarantee?
Answer: Everyone must attain mutual guarantee, but in his own way. Eventually everyone has to be in the same boat.
