Query: not much dressage here

I totally agree with john.davenport's comments. I read this book cover to cover not knowing anything about dressage. At the end, I STILL didn't know anything about DRESSAGE! The contents are just general horse-sense platitudes. But if you want to really understand the point of dressage, what its goals are, and how to begin to make progress towards dressage as a sport and a skill, then this book will be of no help whatsoever.
