Very true. Those exercises sound interesting. I think most people agree about the concept of the existence and/or excess in ego as being a hindrance to seeing and responding clearly in a fight. But perhaps few of us are able to actually understand the feeling of having no ego in our mindset - so your exercises are great in that they lead students to that feeling through self-discovery, which is one of the most powerful teaching tools in leaving a long lasting impression.

I also believe there's a large number of martial artists, however, that have romanticized this sense of "selflessness" ironically to the extreme where it becomes selfish. In their mind they impose on themselves a superficial personality they deem as "selfless", going through the motions of extreme politeness in the dojo and going to the extreme of inaction in fighting as if a martyr. Perhaps because their quest to "selflessness" was all done through the mind the personality conversely becomes more perverse.

In your exercises, contrary to what most beginners would believe, the selflessness within us is proved physically with our bodies.
