"I concentrate mainly on exercising his mind and his memory, in such a way that I achieve what I want: so that it is the horse’s mind which I work the most: the mind of the rider must work perpetually as well, in order to detect all kinds of opportunities to arrive at his goal, without letting any movement pass unnoticed, nor any opportunity unused."
~ Antoine Pluvinel
I take this quote to heart with every horse I ride. There comes a point when the training is more about mastering the horse's mind, his anticipation, his mood, and his willingness to learn than it is about the physical work. I love this video of Nuno Oliveira working with a Lipizzan, keeping the work interesting even at the walk. Alternating between moving the haunches, moving the shoulders and staying alert to all the aids. Notice the soft reins and very calm demeanor of Nuno, you can tell he is totally in the moment with the horse.
