FIND THE MIND AND YOU WILL HAVE THE BODY
Aggression will never achieve this result. Only gentleness and kindness will and can make the horse want to be with you.
It is not the engagement of the rear legs which makes good dressage. It is the engagement of two minds; horse and human which brings success.
The horse knows how to engage its body and the human knows how to ask with kindness. This is a gift given in love and lightness and not some kind of pretense of leadership which uses force."
