Graham, I've read quite a growing handful of your very authoritative discourses over the past year and I have a lot of respect for your tenacity in the face of some stiff criticism. Your OP is titled "My Spiritual Aikido" and as such I don't think I can comment on the objective value of what another person considers his spiritual philosophy. I've never seen Aikido as a particularly spiritual practice but if you do then I think that's great.
However, I also have to say that if you are holding up your spiritual Aikido as an effective martial methodology (which you do in many of your posts) then other folks have every right to ask for a demonstration of its effectiveness. The proof is in the pie, as they say. Can your "oneness" stop a serious attack? If so, how? And can you DEMONSTRATE it? This is a martial art, after all. Peer review in this genre happens when one guy's stuff works and the other guy's doesn't. (And then they go for beers.)
If there truly is a spiritual component to Aikido then it's this: the humility and gratitude I feel when I touch hands with someone better than myself and I learn something. Deep spiritual revelations are great but if they don't translate into practical skills its really all just a philosophy.
Good morning again David. My reply to you part two.
Oneness and for that matter co-existence. Given and presented as spiritual things. Given and presented as inherent in Aikido. Given and presented as not only effective but essential to the efficacy and advanced ability in Aikido Given and presented as unifying and harmonious and the only barrier to doing it is self, no one else. Given and presented as without it there is fight and contest. With it there is no fight, no contest, only effective harmonious action rather than just effective action.
Spirit and spiritual are all to do with harmony and oneness and all embrasiveness and life thus Aikido fits spirit like a glove.
Mind is about data, arguments, memories, storage, survival, rightness, wrongness, fears, compulsions, insecurities, cravings for power etc.etc.
One must let go of one to achieve the other.
