Knowledge

As the room is filled with darkness, as the candle is lit, though the flame is small, burns bright with all its energy , and power it has got, and goes beyond, which spreads, across the room, and lights the room of darkness, therefore a little knowledge, which is spread on, travels a long way, in helping all, and helps in driving darkness out, therefore acquire knowledge, as much as you can, who knows, you may benefit someone, you will never know.
