One becomes an active participant in the world when he or she believes in something. Faith, optimism, and hope—we have to have those things as human beings; otherwise, life is unbearable because there is nothing that we can see beyond ourselves.
It is not outer reality that silence reveals, but our own innerness. Silence is essentially a surrender to the holiness of the divine mystery – whether we use these words or not. An atheist, calming his or her spirit in the peace of silence, is irradiated by the same mystery, anonymous but transforming. We are to listen. To what? To silence.
