I've bought myself a new book, to expand my horizons and further my knowledge, about ground work. It's called Schooling Exercises in-hand and, from my brief flick through it seems to explain how to execute lateral movements from the ground well.
In the introductory chapter, however, is a verse by Rudolph Binding which I thought was worth sharing.
The horse is your mirror.
It never flatters you.
It reflects your mood.
It also mirrors your changes.
Never get annoyed with your horse,
For you can just as well get annoyed with your mirror.
In a nutshell, this verse means that you should never allow negative emotions to surface when around your horse because the horse will recognise the tension and negative energy so will perform badly. Likewise, having a positive frame of mind and positive body language will subconsciously praise and reward the horse, leading to him performing better.
Self-control. One lesson that horses teach us, as well as the ability to recognise when you are not in the right frame to work your horse and instead treat him to a good grooming session or go for a relaxing hack.
