From what I've heard, the type of meditation that Sam harris promotes (or even any meditation really), is very good at teaching you to distinguish between your inner self and your monkey and lizard brain thoughts. It teaches you to concentrate and has been shown to be very good for the brain, even showing a few points increase in IQ in one study (probably from learning to concentrate better).
