Just to hark back to AH's post about riding and how one feels, both mentally and physically when riding and how that might relate to mindstates, I borrowed the below from one of Tagest's posts in his fabulous "Riding in Tuscany" RR elsewhere in these reports (highly recommended for anyone interested in either Italy, or achieving a rather unique way of life in which bikes are a key part).....
"Once, a few decades ago, I tried meditation. The trick, I was told, was to stay awake but "turn your brain off".
Focus on something (an apple, for example) to shut out the normal flow of thought. And then, slowly, you stop focusing
on the apple. The result is that you are there, but your brain is resting for a while.
I prefer a power nap, so I gave that up. But I find that when riding on the Autostrada I fall into the same mode.
I am alert, I am focused on the riding, on the cars and trucks, but I am not thinking.
I see the car and I judge it's speed, probability it will switch into my lane (truck in front of it?), and so on, but I don't
dwell on where they are going, what they are talking about caught up inside, or whatever.
I don't look at the speedometer and say to myself "The arrow is between 140 and 150, so the speed is about 140 km/h".
Instead I look at it and see that it is where it is supposed to be, without actually reading the digits. I know what 140 looks
like, and I don't need to read one-four-zero to translate it into 140.
I feel my brain is resting.
And the feeling of resting, of charging my batteries, as I run down the Autostrada at 140 km/h (87 mph) is fantastic.
Again: I'm not at all running on auto pilot, but I am not thinking either. I don't know how to explain it.
But I can tell you this: I love that feeling of high-speed solitude."
