The Will has to be individuated into an ego in order for effects to be realized in space and time.
The Self could not get to a goal as it was, because it is not the nature of the Self to act. The Self just was and nothing necessarily needed to be done.
The creation story begins when all of a sudden there was something to be done. And the Self created mankind, beings capable of doing. He gifted unto them fragments of the Will subjected to time and space—thus mankind is striving after what the Self needed us to achieve but couldn’t on His own.
