The ass is the symbol of the inertia and obstruction in the body. The horse is the symbol of force or power. The tunnel of water must be the vital physical and the arch is a passage out, by which, if the ass can cross it or rather be pulled across, then it becomes a horse. In other words, the inertia and obstruction in the physical will be changed into Power and Force of Progress.
