If you want to learn how DB does him mind reading stuff look in to doing some NLP training with Eric Robbie

As he trains people in how to read submodalites from the outside, thats what DB does, the book by L. Michael Hall the spirit of nlp as some ways to learn how to do just that.. read submodalites from the out side, if yuo have a few people to work with you can pick a number of things to work with like world flags, 1/2/3/ or more digit numbers, film stars, once you get your calibration skills up, and see that is pretty easy to learn, then you can then play, with guessing people phone numbers and stuff. mind blowing to the out sider.

ok hope this helps some..
