Before listening:

Plan to listen early in the morning, with the sunrise or just upon waking

Listening:

Listen with eyes closed

Walking:

Stand with eyes closed, lean slightly forward and backward on your feet to find your center of gravity
Slide your feet around, feel the the texture of the floor with the bottom of the feet
Take one hand and feel the other
Place a hand on a wall and feel its texture
Keep your eyes closed and make a walk through your home
Use the perception available in your hands and feet to guide you

After walking:

Open your eyes, reconsider your space
What surprised you?
