Nietzsche expounds the original position of “will to power” not merely at the layer of the whole world，but also in various parts of the world.His theory of will to power does not attempt to build a transcendental being beyond the living experience of human.Will to power is not set out of the boundary of individual existence；it is still a kind of empirical factor that exists in human's individual experience.The ultimate aim of Nietzsche's searching for “self” and studying the nature of individual existence is to reach a standard to distinguish meaningful from meaningless.This standard implies the basis to distinguish high and low，so as to help people understand the ideal trend and motivation of their lives.Nietzsche believes that the meaning of life is determined ultimately by will to power；it struggles with other will to power and forms a network of relationship，and meaning actually is the expression of the composition of forces of will to power.
