Training does not teach how to act, how to be clever, does not prepare one for creation. Training is a process of self-definition, a process of self-discipline which manifests itself indissolubly through physical reactions. It is not the exercise in itself that counts—for example, bending or somersaults—but the individual's justification for his own work, a justification which although perhaps banal or difficult to explain through words, is physiologically perceptible, evident to the observer. This approach, this personal justification decides the meaning of the training, the surpassing of the particular exercises which, in reality, are stereotyped gymnastic movements.

This inner necessity determines the quality of the energy which allows work without a pause, without noticing tiredness, continuing even when exhausted and at that very moment going forward without surrendering.
