The learning of the world is built upon a concept of the self adjusted to the 

world's reality. It fits it well. For this an image is that suits a world of 

shadows and illusions. Here it walks at home, where what it sees is one with 

it. The building of a concept of the self is what the learning of the world is 

for. This is its purpose; that you come without a self, and make one as you 

go along. And by the time you reach "maturity" you have perfected it, to 

meet the world on equal terms, at one with its demands.
