Road. How often do you see birds that have been run over. Not often. They have another direction available to them, they can and generally do, go up if there is any need. The words of Jan Cox, and other real thinkers, are kind of like dead birds in the road. By words I mean spoken, printed, words. What can you tell of flight from a flattened mass of feathers? Yet the common asphault is the only means of communication to groups of people for someone such as Jan.
The proportion of birds on the road compared to the sky -- how tiny the number on the road, how vast the song and feathers in the sky. Such, it may be, is the amount a mystic like Jan Cox could say, compared to what he knows.
