To me, the profound difference is that I don't really see Klaus as a horse trainer.

He helps horses find their authenticity back, and then to develop themselves even more. His goal is not to control the horse in the same way as other trainers has a need to, but he makes them more free, and then willing to follow his guidance.

In the same way he gives people following him the tools to become more grounded and able to follow his guidance, without overpowering them with his "power".

He sells books, but no gadgets, he shows people that all they need, they already have inside of them.

And most of all, he is brave enough to stand by his opnions, go against the mass, and not act according to the bill payers will.
