"One does not find wisdom in another's words." -James D. Chye
Since when? I've read many things, heard many speakers, listened to the lyrics of thousands of songs... and I have no doubt I've gained a great deal of wisdom over the years.
What is your definition of Wisdom?
As for Aikido being a path of enlightenment, if you consider "enlightenment" a gaining of ground in the world of wisdom and knowledge (of any subject) then yes, Aikido is a very incredible path toward enlightment.
Will it bring you to becoming "one with the universe"? Who knows? Go ask O'Sensei.
