This symbolism in particular is all over Hollywood. Most of the time, they show the left half of your head (or the left eye) in the shadow, fiery, burnt, etc whereas the right side is shown as the normal, clear side. So what does it represent?
Here is a collection of 'occult' symbolism including the one I have mentioned.
When you balance your right and left hemipheres of the brain a new world of lumination appears. The hands in front of the eye is the first step where you find out which eye is more dominante, It's just the first stage of the process. The 72 degree is when you balnce the brain. It's the point betwen the earth and solar of the three main degrees of moon earth sun.
