If the heart is not clear, mind cannot see clearly (poem)

Yesterday, the cleaners came and cleaned the closed glass windows from outside.
They took off the net, cleaned it and then washed each glass window thoroughly.
While they were doing it, I noticed the slowly increasing clarity through glasses.
But, in one window, where, the inside net could not be cleaned, opacity remained.
