Moths don't know they're flying into a streetlight or campfire. They're innately tuned to follow the light, the moon. But we make diversions for them, we build fires to warm ourselves, and in turn, direct the moths from their moon to their grave.
People do this too. In the process of warming oneself, we create a light which can be witnessed. When we take care of ourselves, we shine beautifully. And others may be drawn to that light, instead of the light which would bring them true happiness, and bring out their own true beauty.
