A large number of the sentences in Thus Spake Zarathustra, specially those in the first and second part of the work, are about  the body or arise from it. This is due mostly to the intensity with which Nietzsche lived the experience of the illness that lasted all his life, because this philosopher found a privileged experimentation ground in illness. In this paper, the author intends to develop some relevant issues on the corporal that appear in the aboye indicated places of the Zarathustra. Also, it intends to show the connection between thought and the creative powers of the human physiological dimension and how this connection is found in the genesis of philosophy. This will be developed in four stages: the exhausted body, the body and it's forces, the relation of the body to that that for Nietzsche characterizes life in general, the will to power as a game of forces, and in the last stage: the relationship between body and philosophy.
