an interesting thought (maybe)
most religions and people are quite easily able to see the body as not self, it's this thing that changes over time, and we have very little control over it. however most people will take the mind to be the self thinking "ahh the mind, the mind i can control". i cant remember which sutta it is in however, but the Buddha actually says it would be more wise to see the body as the self than the mind as the self (even though both ideas are wrong), since the body is seemingly solid, changes slowly, seems like a stable thing unlike the mind which is constantly changing from one thing to the next leaving us with pretty much no control over it, one second we're sad, the next bored, someone drives by and splashes us with mud and now were mad etc. did we control this? did we say "hey i think it's time to be depressed, i haven't felt like crap in awhile"? most of us will say no. this is an aspect of not self and if we're paying attention pretty easy to spot, however most of the time we are just carried along mad sad happy horny depressed grumpy whatever just circling around thinking we're in control.
