It is always important to know when something has reached its end. Closing circles, shutting doors, finishing chapters, it doesn't matter what we call it; what matters is to leave in the past those moments in life that are over.
For the salvation of his soul the Muslim digs a well. It would be a fine thing if each of us were to leave behind a school, or a well, or something of the sort, so that life would not pass by and retreat into eternity without a trace.
You can become blind by seeing each day as a similar one. Each day is a different one, each day brings a miracle of its own. It's just a matter of paying attention to this miracle.
