Re: Why no tsuba?
Stepping back and watching what you are doing is akin to a man caught in quicksand who is digging down underneath himself to find solid ground. People far more skilled, knowledgeable and able than you are pointing out major areas in which they disagree with what you say and what you do. You become defensive and try and wiggle your way out of it with words and then feign puzzlement regarding the use of the internet. You might want to consider stepping back and really listening to what people are saying to you. You might want to step back and consider the necessity of testing these things out with some of these people with an open mind and willingness to acknowledge mistakes, gaps of understanding and lack of ability (For example, Dan's generous and kind invitation to you).
You seem to end up in these situations time and again without any awareness of how YOU are creating this reality. Threads leave the topic and digress to trying to get you to recognize what you are doing to create these impasses. People continue to engage you because they see the positive potential in you. The more you continue with this pattern, the fewer roads will be left open to you. Those roads really do lead to better things. Stop trying to defend what you think that you know and begin to embrace that which you really don't know. This pattern is causing more thread digression than any other thing lately. Kindly step back, take notice and make the appropriate changes for your own betterment.
