A material person says, "Show me something more valuable than gold, more precious than diamonds, something that I can weigh and measure, then I will say, that is God." He understands the brightness of the diamonds, the value of the gold. But the gold has only the value that we give it. In itself it has no more value than the iron: we can make more things of iron. But we like it, we like its color, it has a radiance. It is the same with all things.
