Training takes a lot of patience, bonding with horses doesn't take much. By using natural herd dynamics one can bond with a horse in mere minutes. If you do not KNOW whether or not your horses are your partners and willing volunteers, they aren't. Once you have established this connection and learn to work within it you are able to accomplish things much faster and easier. Once bonded all the other stuff gets so much easier.
Communication is so heightened, it is spooky.
And communication is key to prolonging and deepening the bond. If so, your horse is bonded.
