The main force that drove him was a realization of suffering, and the core of his teachings was an understanding of the nature of suffering. "Enlightenment" in the Buddhist tradition may or may not bear any resemblance to whatever Ueshiba called "enlightenment". The term is commonly bandied about in the west and used for different things. I don't think there's necessarily any commonality there.
So are you saying that there is a difference between the Buddhist view of enlightenment and Ueshiba?
what are the differences if so?
