One of the techniques that works great for me in getting into the "ideal state for learning" is as follows (I learned this from a mind enhancing book several years ago, and have adapted it to PhotoReading)
1) Close your eyes
2) While keeping your eyes closed, rotate your eyes 40 degrees toward the top of your head. Pretend you are trying to look at your eyebrows from "inside" your eye cavity.
3) This will immediately get your mind into a natural relaxed state; and your eyes will feel very relieved (kind of like your neck feels when you get a neck rub)
4) While keeping this posture you will immediately begin to feel a sensation on the top/back of your head. All you have to do is imagine it's a tangerine sitting there.
5) Take 3 deep breaths, relax your body.
6) Remind yourself to "widen your vision"
At this point you should have reached the "accelerated learning state". Furthermore, as you get used to this technique; all you'll have to do is: Close your eyes; rotate your eyes "feel the tangerine", and take 1 deep breath.
