Refraction...

Refraction explained as.... the bendinig of a ray or wave of light or sound,as it passes from one medium into another.... Example, a clear glass half full of water with a straw inside glass as light passes through the glass it creates an illusion of sight the straw appears as two seperate but,if you hold straw straight center it become's as one straw again. Theory, if we look at our physical body as a container filled with water if we consider our spiritual self as above example,being the straw you can now understand the importance of centering,focus the farther we lean in any direction creates the illusion of spiritual sight with the possibility of a broken spirit The Holy Grail,or cup is our physical body containing our Holy Spirit....
