Looking Inward Through the Eyes

Sit with the eyes open and softly fixed on any plain surface, a wall, a clean floor, a piece of cloth. Begin by simply looking outward as usual. Then, slowly, reverse the direction of attention, while the eyes stay open. Instead of looking out from behind the eyes, sense the looking moving inward, as if your attention is now travelling back into the head, through the eyes, the way light could move both ways through a window. Stay with this reverse looking. Things are still seen, but you are home, behind them.
