Engaging read; some blinding glimpse of the obvious, some eye rolling, but in general a balanced approach to what can sometimes be a new agey woo-woo topic: Natural Horsemanship. Rashid himself eschews this term. As he indicates, there's nothing natural about climbing on a horses back and asking them to do anything. The notion trying to see where the horse is coming from is an important one for good horsemanship, and this seems to be the road Rashid travels.
Probably the thing I find most irritating about any of the western riders who discover natural horsemanship is the epiphany that happens the first time they break a colt quietly, without a huge bucking fit. Honey, hate to tell you, but people have been backing horses quietly from the time of Xenophon. I've watched horse backed for forty years (and backed a few babies myself) and have never seen one pitch a fit. It's the way things have been done properly for millennium. So, nothing new there.
Overall, the stories are entertaining, and Rashid does come across as a reasonable, humble person who enjoys telling the stories about what he has learned. There is a lot of oblivious horsemanship in this country; if it takes reading a book or taking this man's clinic to change that, all the better for horses. He's not selling toys, or equipment, and genuinely seems to want to see people ride their horses, so head and shoulders over the delusional Parelli crowd. A worthwhile read, for entertainment and a few insights.
