That's a good translation, though I would reverse it: "The way of harmony of spirit/energy". A subtle shift, but to me that emphasizes that it's a practice. You can't fully embody "the spirit of harmony" (in my experience), but you can practice "harmony of spirit" or "harmony with energy" often.

It's worth checking aikiweb if you're looking for dojos near you. The website looks dated, but they keep the database updated: http://www.aikiweb.com/search/index.html
