When working with the horse, you turn inward, and you turn outward - both. Time disappears and you can't remember if it was 'it', that happened.
You ask me:
"Will the result of the work show?
Has the horse perhaps discovered 'it' in me?
Will my body and the horse's body remember 'it'?
Will my body recognize 'it'?"

Look, there's no going back. Practicing is the practice. The horse is waiting, your body is waiting.

You want to know if this waiting makes sense.

No, that is too strongly put , because 'it' is not known, is not felt, but you shall walk towards 'it' with ease and with confidence. Then something will be built, created, something natural.

"What is it?" You ask.
