If the world is a temple, then our enemies are sacred, too. The ability to respect the outsider is probably the litmus test of true seeing. It doesn't even stop with human beings and enemies of the least of the brothers and sisters. It moves to frogs and pansies and weeds. EVERYTHING becomes enchanting with true sight...All we can do is to participate.
It is possible to enjoy every step we make, not only during walking meditation, but at any time, whenever you need to move from one place to another, no matter how short the distance is.
