The First Innovation
All the innovations begin only once a person has been rewarded with emerging from self-reception. This is the meaning of the prohibition to teach Torah to idol-worshippers, since when a person is in Egypt, he cannot be a Jew because he is enslaved to Pharaoh king of Egypt, and when he works for Pharaoh, he cannot work for the Creator.
This is the meaning of “For the children of Israel are Mine; they are My servants,” and not the servants of a slave. When a person is his own servant, he cannot be a servant of the Creator because it is impossible to serve two kings at once. Only once he has come out of Egypt, meaning from self-reception, can he be a servant of the Creator. At that time, he can be rewarded with the Torah. It follows that the first innovation is the exodus from Egypt.
