I don't know about the celestial tea cup or Rokus training. But here's some insight. As you watch or listen you'll start to pick up a lot of red flags.
9:14 is what I've been saying all along. "finding answers by myself" His words not mine. You can also see that he did not identify his goal of "best martial artist in the world." He keeps thinking that it means being the "best student" You can hear him repeat it over and over.
This is what I was saying about Aikido. First identify what Aikido is. Aikido isn't just one thing. It is not the same for all Aikido Practioners. This is why I keep saying that I see 2 camps of Aikido. So while we say that it doesn't work in one camp, this may not be true for the other camp.
No he's not.. He pretty much says so in his video as there is no mentioning any sparring in any of the schools he trained under. He comes from the Aikido Camp that doesn't believe in competition. Because of that there is no way to be the best fighter or worst fighter. When everyone wins a trophy then no one is better or worst as defined by "Wining a trophy."
He also made some TMA mistakes. Like never ask the teacher can he improve the techniques and never tell the teacher that you are going to train in another martial arts system. It's better to just do it without telling the teacher everything you do with your life.
There are a lot of aspects of my own training of Jow Ga that I didn't share with my teacher. I figured it was none of his business. It was my personal journey into Jow Ga. I know it shouldn't be like this, but if you understand TMA environments. They have more EGO than they claim. So it's just better to just keep some things to yourself.
