In horsemanship, we are aware of how many elements are involved in good horsemanship. There is the health of the horse, the fit of the equipment we are using, our skills as a rider, our relationship with the horse… each matters equally, and the more educated we become as horse people, the more clearly we see the importance of all parts of riding.
Each of these areas has its own parts as well. For example, for the health of the horse there is nutrition, hoof care, dental care, fitness and conditioning. Each may be examined individually but is also always part of the whole.
The same exists for our part as a rider, we need physical skills, fitness, a certain level of knowledge, and mental skills too. This is where an interesting parallel is seen in the principles of yoga, specifically in a concept called the eight-limbed path, which describes the principles of yoga as a guide for life, beyond postures and movements.
