There are two parts to your vision – the central part of your vision when you look at something is called foveal vision but around the outside of the foveal vision is the peripheral vision.
If you are actually in the state of peripheral vision, with your awareness expanded outward what happens is it opens up a trap door to your brain and all the information can flood straight in. Being in this state increases learning and it increases recall so it is called the Learning State. As learning is state related, when you want to recall the learning you simply recall the state (awareness of things in your peripheral field of view).
Pick a spot on the wall to look at, above eye level, and as you focus all your attention on that spot on the wall notice that within a matter of moments, not just yet, but in a matter of moments you attention spreads out into the peripheral.
When your awareness has spread all the way out into your peripheral notice that you can actually pick out an object on your far left and an object on your far right and hold them in your awareness at the same time as you keep your awareness in the peripheral.
You can then bring your eyes down and look at the people around you. Still looking straight ahead you expand your awareness even more so you can see the person on your left and the person on your right. You can actually see both of them at the same time. That is called the learning state.
This is great to teach kids for when they in the classroom. When they enter the learning state, they can recall all the information later during exams easily and effortlessly. It works for training courses too!
