If I asked most people to draw a picture of a horse chances are they would draw a head attached to a neck, attached to a body, attached to four legs, and finally add a tail, ears, eyes, etc to their masterpiece.
I have described the goal of teaching a horse to let go of an idea and then teaching it to accept a new idea as being fundamental to achieving “oneness”.
Every horse is a horse. They are not showjumpers or carriage horses or plough horses or gaited horses. Every horse is a horse and that should be good enough.
