Lol I love Si's posts. Have had similar encounters. Always dropped em harder the second time.
I voted No btw.
I think a human being can find spirituality in everything from a glass of water to a rock to a mountain if they look hard enough. However it is difficult to see how techniques that are basically modified Jujutsu are "inherently" spiritual. "Inherently" being the operative word.
How one approaches their art and their practice can be an entirely different thing however and one can choose to have a practice with a spiritual focus. But this does not make the techniques inherently spiritual. In the end it is up to the mind of the individual that determines the approach to Aikido.
Just a few thoughts.
