A few years ago our family went on a long boat trip. I had been looking forward to it, but I was also apprehensive because I feared motion sickness. Sure enough, not long after we set sail the boat began rocking, and my fear played out as I experienced the symptoms of seasickness for the next day and a half.
Staying in my cabin, I read the Bible, Science and Health with Key to the Scriptures by Mary Baker Eddy, and issues of the Christian Science magazines. Praying to see more clearly the omnipotence and omnipresence of God, I affirmed that since God is all-power and fills all space, I could experience nothing but good.
These ideas were helpful, but the inspiration that suddenly woke me up was remembering how videos of wild motion, such as simulated roller coaster or sail gliding rides, would make me feel just as nauseated. Then I realized that the rolling and rocking of the boat was the same—just a movie that the material senses were presenting. As mental pictures, this imagery was powerless to affect me without my consent.
