There is a place in everyone that can carry the light. God has made it this way. God has not only given us the chance to carry the light, but has made it possible for us to kindle and strengthen the light in one another, passing the light along. This way God's light will shine forever in this world.
I have learned to understand time and thought as a spiral: neither a straight line that must go always forward, even into a precipice, nor a circle that must remain forever stuck in repeating past experience. Instead, a spiral, which curves always backward in order to curve forward. What makes time and life into a spiral instead of a straight line or an endless circle is setting aside time for reflection, rest, renewal. That renewal time is the curve that moves the spiral onward. This lets us re-view where we have been, so that we can go forward.
