Outsiders are allowed to peer in the window of churches, temples, mosques, and synagogues. Those inside then have a choice: slam the window shut or open it and let in some light.
I believe Deepak Chopra's novel about the Prophet does the world a great service. In the midst of escalating suspicion of Islam, the book humanizes the religion's leader for those who do not yet know him, a man adored by billions.
When I began to research the origins of Islam, I found that compared to what I had absorbed about the life of Jesus or Buddha, my knowledge of the Prophet's life was almost a blank.
