Do you remember
The 21st night of September
The song 'September' by Earth Wind& Fire was written about an epiphany. The very elusive subject of enlightenment. Clouds in Eastern culture means the unwise mind. The clouds of thought that try to hide the sun from our eyes. Suddenly you remember is recalling this epiphany, that inner happiness that will never be taken away.
