It certainly is - for me - "The Way of Aiki "
Once I thought
could be interpreted as "the way to look for aiki", now I prefer to think of it as "the way to express aiki".
There are many other ways to express aiki, so if you look at it that way, then Aikido would be only "a way to express aiki."
I'd say that it's more "the way to transcendence, through the practice and refinement of aiki." Aiki as The Way (to Enlightenment). So, "The Way of Aiki."
