The symbol is a unalome, a representation of the journey to reach enlightenment. The path starts in the centre of the spiral, and as you continue up or down this path you are wandering, becoming more conscious of your surroundings.
I have an obsession with eyes. I do believe that they are the windows to the soul. I draw eyes in a lot of my notebooks and on almost all of my school work. I find them so. I hope you like this awesome pic of a lot of this colorful eye :)
