Which Founder's bio are you working with?
I was just looking for the quote about golden lights so I googled it. I first encountered the golden lights in the Stevens work, I am pretty sure I have come across on Aikido Journal, and the one that I grabbed was in Ueshiba's wikipedia entry and is cited as coming from Kisshomaru's book Aikido
published in 1985.
Checking the wiki entry again, it is placed as happening after his bout with a naval officer in 1925 when Ueshiba walked into a garden. I think this is pretty standard for everywhere I have read the story.
I guess the hypothesis I am trying to discuss, though, is that there are different technologies, one that enhances spiritual enlightenment and discovery, and another that enhances body skills/martial capabilities. They may use some (or many) of the same tools and materials, but the end results could be very different products.
