The beginning of this post can be found in: Passover Is A Reminder Of The Future
Abraham’s group moved to Canaan.The ego then grew from one generation to the next, but the main thing was to keep the general connection, the spiritual brotherhood.
Later, the disputes and conflicts grew to such an extent that even Jacob’s sons, the brothers, couldn’t overcome them. This process is described in the Torah as the beginning of the famine. The brothers sell Joseph into slavery in Egypt, (Mitzrayim), which symbolizes one’s evil nature (Yetzer-Ra). When they fell from the level of brotherly love, they found themselves under the domination of the ego, Pharaoh.
At first this domination was good: Pharaoh raised Joseph and life was full of different pleasures, but then things changed and people began to feel that corporeal benefits and pleasures were not everything in life.
They felt a deficiency for a spiritual connection, which Pharaoh, of course, objected to and resisted. Now all the ego’s efforts were not to allow them to maintain even one bit of inner unity.
It seemed as if there was no way out, but it is actually the despair that generated the force that pulled them to unity—Moses. He was brought up in Pharaoh’s home, the ego, and was therefore ready to confront the king of Egypt. This spark that kept the essence of the Jewish soul lives in each of us. It is the general, inclusive perspective of a united world in which there is no room for separation.
