The Zohar, Chapter “Bo (Come unto Pharaoh),”… And the Lord your God brought you out of there..Remember this day in which you went out from Egypt…And brought thee out with His presence, with His great power, out of Egypt…The Lord brought you out from this…Fifty times is the exodus from Egypt mentioned in the Torah….
Fifty is the full degree, the ten Sefirot of Malchut together with the forty Sefirot of Bina. Malchut in its entirety needs to rise above itself, to its full degree. These two forces need to be felt inside of a person – one against the other.
Therefore, salvation will not come until we end the exile, after reaching a horrible sensation that we have no strength to exit our egoism, and feeling at the same time, it is absolutely necessary for us to do this! When we will feel this opposition to the full extent, the waters of the Red Sea (in Hebrew called the Final Sea) will open up, and we will cross it.
A person doesn’t know how it is revealed. This is called a miracle. However, this miracle is caused by the person himself, when he comes to a dead end. On one hand, a person doesn’t understand how it is possible to exit – he has no power or strength for this. Furthermore, he doesn’t understand that there can be some force from Above, which can somehow change his nature. On the other hand, this force that exists above nature is revealed.
This occurs only like a miracle. It occurs above that state, that nature, which is called “Egypt” and comprises the whole inner sense of a person.
