(excerpted from page 70). . . from the FEI Rule Book, Article 401:

The object of dressage is the harmonious development of the physique and ability of the horse. As a result, it makes the horse calm, supple, loose and flexible, but also confident, attentive and keen, thus achieving perfect understanding with the rider.

The horse thus gives the impression of doing of his accord what is required of him . . . he submits generously to the control of the rider.

He responds to the slightest indication of the rider and thereby gives life and spirit to all the rest of his body.
