The song of the field is the buzz of the mind
            of the man in the field.
To enter the mind, enter the field.

But the song in the mind is the hum of the woods
            at the edge of the field,
and to enter the edge, you must enter the woods.

But the song of the woods is the caw of the crow
            at the top of the pine
and to enter the woods, you must enter the crow.
