"The words of the prophets are written on the subway walls and tenements halls and whispered in the sounds of silence"

In this quote, Paul Simon is recommending that the messages of the prophets, or wise and spiritual leaders, can be found in unforeseen places. He points out "train walls and tenement halls," which are frequently associated with urban and lower-income areas. These are not generally seen as places of great knowledge or enlightenment. Nevertheless, Simon believes that even in these apparently ordinary and overlooked areas, the words of the prophets can be discovered. He also mentions the "noises of silence," which could describe the quiet minutes in between the hustle and bustle of city life. This quote advises us to look beyond the apparent and listen closely, as knowledge can be found in unforeseen places.
