He may not understand or be aware of it.
When I was about 15 years into my journey with horses, it became apparent to me that I could catch horses that others found difficult to catch, and ride horses that others found difficult to ride.
I’m no master, I promise. I don’t even pretend to be one on tv.
What I’m naturally very good at is body language and reading equine signals, which as those of us are experienced know, are very subtle.
I underestimated (at the time) how much body language I was using with my horses. So I was clueless as to why horses that were difficult for others were easy for me.
What tuned me in finally was trying to help someone else longe and realizing they had their body and energy all wrong. So I had to figure out how to help them get it. Then I encountered more people who could only longe the well trained horses, and realized they didn’t know how to stay balanced in the drive line or how to block movement etc.
I do think that part of what Hempfling says (without the melodrama) is somewhat correct. If you are not aware of what your physicality is presenting to the horse you will have more difficulty than someone who is aware.
But a good coach can help one understand that.
I do think in part this is something that often separates the naturally talented from the not naturally talented, but again, it can be taught. I focus on it in my lessons but not to the exclusion of correct techniques. And I certainly don’t mystify it, I just speak to the fact that I’m using a language that horses come wired with. shrug
