Where I'm coming from is that you stated that Tohei got certain things from somewhere specific. If you don't want to argue that when someone calls you on it, then don't make the statement.
O.K. Chris. I am coming from understanding. I find the 'call you out' approach strange. I do so in life too, I usually smile at such things and walk away.
I suggest you study and practice some shin shin toitsu do, go to some classes and then come back to me and tell me about how they practice those principles, how they test them and use them.
Nothing to do with 'sources' , no argument.
