You would mistake him for a beggar, but that he has not asked for anything. What he seeks cannot be obtained and for this reason he needs nothing: no coin, no bread, not even your greeting or your gaze. He does not speak to you as he passes, but you hear, as though the wind spoke out:
You need your need.
The empty space inside you that drives you from the crowd into the desert.
It is impossible to follow him. The only way is to turn away from him and walk out alone into the night. Trusting your own light.
