The defense perimeter of the eyes works with you to build the perimeter of the mind. The mind needs an object for its lust, so when the eyes view sexual images, the mind has plenty to dance with. Without those images, the mind has an empty dance card. By starving the eyes, you starve the mind as well. Although this alone is not enough–the mind can still create its own lust objects using memories of movies or pictures you saw years ago or by generating fantasies about old girlfriends or the women with whom you work–at least with your eyes under control you won’t be overwhelmed by a continuing flood of fresh lust objects as you struggle to learn to control your mind.
Today I will consciously guard my eyes to prevent new input from overwhelming my mind.
