Thanks Aloka, I liked that quote from Ajahn Chah, but it perhaps need unpacking for my unsatisfactory brain
In regard to nails, do we just have to consider them for a few moments until we see how they are impermanent, unsatisfactory and not-self? So ... nails are impermanent, obviously, we need to cut them, unsatisfactory... it's hasstle cutting them, cut badly and it hurts! They are about obviously not a part of your essential self, cut them and is there any loss of self?!
So do you just go through the 32 body parts in this way, once, and that's it, job done? Can you now get on with anapansati and forget about doing "body scan" meditation?
Is brain one of the thirty two body parts?
Problem... you never see or feel a brain, unless you go to an autopsy!
Is watching CSI a good idea? You see a lot of unsatisfactory, impermanent brains on that programme, and you see any possible "essential" self is gone after the shooting, or whatever...
