Dear Mia,
The music is the analogy is for what is felt. As one operated in a certain way in the concert hall to deal with what was felt then so one operated in that way in life. The music was the inspiration and suggestion for that. I'm not sure if my meaning there was clear. It was not about abandonment although that would be a part of it, perhaps coming at the end of life, to a terrible disease for example. You talk about thunderstorms and then having the reflexes to wear one's power lightly…
The best way I can answer this is probably from experience. It probably isn't useful to describe exactly how one does it because that would be different for different people so one would have to take what is needed from what follows here. Some years ago I was in a train and a group of high school students from a private school accompanied by their teacher came on and sat down. Shortly afterwards, a tall muscular gentleman of skin head appearance pushed past the teacher and started hitting one of the students. Chaos ensued, much screaming and fear. "Skinhead" was extremely angry. I was sitting a few feet away. I reached out to his arm and pulled him away from the boy. The grip was deliberate, controlled and released almost immediately. I didn't want him pulling back. He then directed his anger at me, shouting all kinds of expletives. I didn't hear them very well because I do have a hearing loss. I was still sitting down whilst he stood there, full of rage. I was calm and controlled and stared back at him. The situation detoriated and it was an eyeballing contest. He was aiming to hit me so I followed his arm with my eyes to his fist and then looked into his eyes. He knew that I knew what he was feeling. I kept ahead of him in that way, my eyes playing to his body all the time. But he wouldn't let up, it wasn't working so I began to mirror his anger. That was not difficult because as the situation had escalated I became more relaxed so I only had to let myself become worked up by letting him have an effect on me. A kind of hot burning anger began in my stomach region and rose upwards, heat spread through my body. (I added to it by thinking of my parents who were dead). This was the fight/flight response. My face was colouring, I could feel it. I felt stronger and looked at him in a different way, where anything was possible. From eyeballing, this was now like two wild animals facing off. I was also becoming hyperaware and saw and felt a great deal. His left foot came off the ground and he stepped back. Instantly I said "thank you". To cut to the end, within a minute he ran out of there. Very few words were exchanged and I didn't get up off my seat.
I could do that because I remained calm due to MA training. The control was over myself and over this gentleman. You learn that from training. But not everyone can do it. With experience you get better at it. You become familar with your body and it's responses. You can even have significant control over it's responses. Self reflection upon one's feelings helps but in the heat of the moment, virtually all thinking ends and you depend on feeling almost entirely, that is why training is necessary. There is no time for thought and the moment may seize you and take you with it. If that is not on your own terms you may be in serious trouble.
How does one cope and abide with the world as Emily Dickinson asked? With sensitivity but not being dominated by the feelings thus engendered. Whitman accepted feeling, welcomed it, gave rein to it and trusted in it. One lives with life. Tough and tender minded, I remember William James rather than his brother Henry. He said other things about conflict and the importance of attitude.
And a thing I found is that one only learns these things - responding in the moment - by actually doing them. There is essentially no other way. Reflection and thought afterwards helps for future times but it is no guarantee of change, by itself. So in a nutshell the answer is to experience life and think like hell about it afterwards. I'm only 45 and as I get older it is true, one wishes one knew now what one knew years ago. Like they say, youth can be wasted on the young.
I hope you can make use of my answer, it's terrible I know but I guess if it were easy, we'd all be doing it. Your questioning strikes a chord in me and I admire your intention and spirit. May it ebb and soar all your life long.
With love,
Martin
