We are pilgrims bearing candles through a vast and dangerous land, on a journey none of us will ever complete.
In the dead of night, when all is darkness, you always have your candle. Though it is dim and flickers, if you attend to what it shows, you will never put a foot wrong.
But if you keep your eyes downcast upon your candle in broad daylight, though the way may lie open before you, you will not see it. The small circle it reaches is not the world, not even a tiny part.
