P.S. on sleep
The last tricky piece of the puzzle about sleep, for me, is the difference between a traditional model of how the body works, and the tensegrity model. In the traditional model you have activity and effort, and then you 'relax' to recover from that activity and effort. Activity and effort involve exertion and 'doing' things, and relaxation is a sort of collapsing and doing-nothing.
In the tensegrity model, which is how our body works (it just hasn't flowed through into the common biology teaching yet), there is no distinction like that. Both activity and what looks like non-activity e.g. sitting or lying down, involve exactly the same mechanisms. You don't have to exert yourself to do things, like walk or run or lift something, because your whole body is elastically pre-sprung to release into those sorts of things, you just need to let it.
This was a challenge for how to think about sleep, for me. In the traditional model you go to bed and you collapse and relax, in the traditional model. But if you use your body as a tensegrity system, you don't ever collapse like that, you just are, in whatever you're doing. So once I'd learned that, hopping into bed was quite strange, because I'd lost that need to 'relax'. So it was as if I had to reinvent what it meant to sleep.
That seems to have developed now, to some sort of understanding. I needed to drop that need to feel like I had to let go of something, like the day itself and tiredness. It was a different way to think about tiredness, just as it makes all the difference in the world to think of disorder not as the opposite of order, but as the creation of a new order i.e. there are only orders (plural), not order versus disorder. The universe as a whole doesn't work in those good versus evil, order versus chaos and decay sort of way. And nor does being awake and being asleep, there seems to me to be much more a continuity there than a division.
More on that next time.
