"I think, therefore I am" may be a pointer to some that your thoughts and actions can, after years of training, become one; but it's a false promise...because your body is incapable of any meaningful action without first receiving a signal from your brain. Besides, apart from the quote above being misleading (it has been edited), thinking first and acting second is way too slow if your fighting for your life, or hope to save yourself from serious injury.
Without being sententious, a budoka who cannot develop a 'feeling' for what they do, has little hope of applying their art in a martial (or any other) sense, and as such, no amount of learning and knowledge will suffice. Indeed, there comes a time in the life of all serious budoka, when they will have to make a choice: remember everything they have ever learnt, or move (live) according to what they have absorbed.
I think understanding budo stems from understanding yourself...
