Why do you ask? In history there have been some or many and today there or some or many. What's your point?
There are lots people believing lots of things. Good for them.
I asked for powerful people using that as meaningful to their budo. The people don't exist in budo
because the model doesn't work for anything meaningful to develop a budo.
Anyone can "believe" anything they want, fine by me.....right up to them landing on their heads.
For anything meaningful in doingBudo
this is a dead end.
