That which you state above....is a religion to some!
Religion is defined by the person.
As a Buddhist, I belong to the religion of non-religion. Buddhism is by many considered a philosophy, by others a religion.
Same with Aiki or Aikido...to some it is a religion to others it is a work out, still to others it is a way of life.
What difference does it make if we define it?
I think people, westerners in particular, place far too much emphasis on labels and trying to fit everything in nice neat little boxes.
