Answer: A person has to be ready for it. He has to be able to hold on as he encounters increasingly greater blows. Moses is our innermost point that begins to work when we can connect. It is the point of our inner connection that leads us.
The only thing we have to worry about is the point of connection, so that we can later raise it to Mt. Sinai and receive the whole revelation of Godliness in it. Then it will lead us forward from the center of the group where everyone is equal and we are all connected. We all annul ourselves with regard to this central point of the group and establish in it the vessel of the soul. This is actually the whole method.
