You might enjoy a book called Quantum Psychology (Robert Anton Wilson).

He lays out some interesting concepts about the way we think and one thought experiment in particular, observing all the 'thinkers' within and how they can multiply at will i.e consider the following innocuous statement:

"I observe that I am happy"

Who is happy and who is the observer?

Eckhart Tolle may say the observer is your conscience and who is happy is your mind. That's a guess though. :)
