When a monk goes away from the world, he goes fighting with it. it is not a relaxed going. His whole being is pulled towards the world. He struggles against it. He becomes divided. Half of his being is for the world and half has become greedy for the other. He is torn apart. A monk is basically a schizophrenic, a split person, divided into the lower and the higher. And the lower goes on pulling him, and the lower becomes more and more attractive the more it is repressed. And because he has not lived the lower, he cannot get into the higher.
