The Apes were Surprised
Humans did not emerge on this planet through apes following their tried and true ape scripts. But nor did the apes get together to try to figure out how to become human. Real change emerges from the mysterious Source of creation Itself; we don't have to invent it. But unlike the apes, we can choose to open ourselves to It.
The Torah tells us that the Israelites had to become free from Egypt first, then receive the revelation of their mission at Sinai. It is the same for us: in order to receive our missions directly from the Source, we must first free ourselves from the contracted sense of "me" and "my life", and that means letting go of all our assumptions. The "I" must become an open window through which the breeze of Divine evolutionary impulse freely blows.
