No Self

It's hard for me to totally wrap my brain around the no-self concept but I've thought of this example:

DPI, dots per inch. When you print a picture of a person out of a printer when you look at the picture and you see a person. However if you look through a magnifying glass you see that the photo is really just thousands of little dots. The idea that all those dots combine into one thing is an illusion, so too is the idea of an "I" an illusion.

That example is somewhat limited though because it doesn't really demonstrate the idea that the dots are constantly changing, so to further develop my example imagine that not only is the picture made of dots but that the dots are also fading. The dots are like all components that make up "you" they're constantly changing and they're not connected. There's no part of the picture, or you, that's the same from one microsecond to the next, so how is it logical to say that the picture from the printer at 4:00 is the same as the picture at 5:00? All of the dots have faded, they've changed.

The picture has no self no atman, it's just a group of dots, and those dots are constantly in flux.
