The yoga teacher says: With your eyes closed, cross your eyes and gaze at your third eye.
So cool on so many levels.
Usually when I meditate, I focus on the light between my eyes. The light that once glowed blue for me has lately grown pretty dim. Another technique I use is to imagine a magnet in my chest drawing my thoughts from my head to my heart.
Crossing closed eyes takes special concentration. I feel the confusion in my little eye muscles as they strain against each other, against what is possible.
