During my last term of college I suddenly lost my sight. I was aware of large objects but could only see in focus for very brief intervals and under significant strain. In addition, I would experience random outbursts of pain.
Very few people were aware of this problem. Even my roommate had only the vaguest notion of what was going on. At first I felt frustrated that no one seemed to notice my difficulties, but I quickly became grateful. I realized the importance of praying directly and quietly to God.
During this time, I requested treatment from a Christian Science practitioner. We prayed with the idea that my consciousness could not be mesmerized. In other words, because the active healing presence of Christ was constantly speaking to my thought, I couldn't be lulled into believing any thought that was not from God. We also discussed the ability to recognize, and thus control, illusions.
