I've studied the works of Alan Watts, the man who introduced Zen Buddhism to the west. He said that the fact that you can't control your thoughts --only acknowledging them-- is in fact the demonstration that we are not the mind.

Another interesting, yet somehow terrifying thought experiment Watts used to teach was as follows: suppose you have a craving, an urge to, say, smoke a cigarette. When you recognize that intense craving for a smoke, and then ask yourself this transcendental question:

"Who wants to smoke? "

The answer will come, and it can be either terrifying or aye-opening:

It is not YOU who wants to smoke. It's something else, it's either your body or your mind, but but not YOU.

The real YOU is like a child who stares with awe before a beautiful waterfall without making any value judgment or forming any opinion. That little moment when you feel pure bliss when you hold a baby in your arms, that's the real YOU. Everything else is the mind.
