SHUTTLING THE "O"

1. In your mind's eye, that is, with eyes closed and in memory, draw a big black round .
2. On the left black curve put a black dot; on the right curve put another black dot. The black dots on the "0" will be lost in the blackness but you know where you puts them so you can return to them in memory.
3. Do just that, pointing your nose and attention from one dot to the other, from one black side of the "0" to the other, from side to side until the "0" seems to out of your way as you travel from one dot to the other dot.
4. Now put a black dot at the top of the opposite, on the bottom.
5. This time direct your attention to the top dot, then to the lower dot-top to bottom. - The "0" will seem to rise and Does this illusion of motion come? When it does come, it will prove most restful.
