Taking your time, translate each of the following descriptions into a mental image. Go back and do it again in a few weeks and then a few weeks later, and notice the difference. Notice the difference, also in the way you see things--inner as well as outer-- after you've done these exercises.

Now sense(see, touch, hear, taste, smell) with your minds eye:
a familiar face
a galloping horse
a rosebud
your bedroom
a changing stoplight
a newspaper headline
the sound of rain on the roof
    the voice of a friend
    children laughing at play
the feel of soft fur
    an itch
    a gentle breeze on your face
the muscular feeling of running
    of kicking a can
    of drawing a circle on paper
the taste of a lemon
    of toothpaste
    of a potato chip
the smell of bacon frying
    of a gardenia
    of perspiration
the feeling of hunger
    of a cough
    of coming awake
a stone dropped into a quiet pond with concentric ripples
    forming and expanding outward
these words flying away, high into the blue sky, finally
your shoe coming apart in slow motion and each piece drifting
     away into space
an orange being cut into five equal pieces and the pieces
     being arranged into equal patterns
