Hold your hand in front of you and imagine your hand is a fish.
Look at the fish, and let the fish look around the room. Imagine that you can see what the fish sees - focus.
Let the fish lead. Your arm follows the fish, and you follow your arm - fixed point.
Imagine what the fish is seeing, thinking. Think what the fish is thinking. Breathe with the thoughts - breathing.
Follow where the fish takes you.
