The advice in this book was to sit with my eyes only partly open, gazing downward at a spot about 3-4 feet in front of me. I tried that and found that my eyes kept jerking to the right, as if they were suddenly speed reading. Has that ever happened to you?
Then I learned to soften my focus a bit and that helped. However, my eyes would then get heavier and heavier and want to close. Blinking every breath or two helped that.
After I softened my focus, I found that I could still have an awareness of the outer world while maintaining my primary focus inward. Ta-da! That is probably the whole point -- to learn how to keep an inner focus while in the world. Now, all I need to do is practice, practice, practice.
Maybe then my eyes will finally have it.
