Q: Where does the correcting force come from, and how exactly does it do it?
A: In order to help climb to the next degree, the superior degree lowers down its bottom part, called AHP (Awzen, Hotem, Peh), to the degree below it. As result, we realize how we should change, how we can be corrected and where to receive the strength for it.
The correction is performed through the Surrounding Light, since in the lower vessel there is still no screen in which to take the Light. Just think about it: if it could take in the Light, it wouldn’t need to be corrected, would it? The correction always comes from the superior degree, to which the vessel should rise when it is not yet corrected. That is why the correction is always induced from the outside, through an Upper Force that works as a Surrounding Light.
