I am not asking you to not leave those perspectives unchallenged. Many of us who came to the Aiki Expo came to challenge what we experienced and left with a painful awareness as to things way beyond what we thought we knew. That same process is alive and well with me in my continued training with Imaizumi Sensei, Ushiro Sensei and Dan Harden. As much as I would have liked to have disproved much of what I have experienced and gone through, I am left with an awareness as to how much more there is to discover. Ushiro Sensei, in his profound book "Ki and Karate", points out that the major impediment in what we can learn is what we think that we know. I have come to the point where I don't have to possess a complete paradigm of understanding for what I am experiencing to recognize that with patience and hard practice, I will gain a much better understanding of things that I am currently experiencing. I think that many of the more seasoned people here have been trying to help you to recognize this arena.
Matthew, Marc is a very eloquent guy and very direct at the same time, and he knows what he is talking about (he is also a little goofy, but we won't go into that at this time
) the point is (and this is not negative in any way) is that you are young and have a lot of opportunities ahead of you to grow and learn - do not shut off potential avenues of knowledge by discounting things at this early age simply because you do not understand exactly what is going on - I did that many years ago and essentially found out out later that I wasted 35 years of opportunity because I thought I had the right answer at that time. Things change and you change - get out and explore more if this is what you are interested in - IMO, if you maintain your current position on aspects of ki, you will not be in Aikido, or any internal art much past a few years from now.
