"Desire can be compared to fire. If we grasp fire, what happens? Does it lead to happiness?
If we say: "Oh, look at that beautiful fire! Look at the beautiful colors! I love red and orange; they're my favorite colors," and then grasp it, we would find a certain amount of suffering entering the body. And then if we were to contemplate the cause of that suffering we would discover it was the result of having grasped that fire. On that information, we would hopefully, then let the fire go. Once we let fire go then we know that it is something not to be attached to.
This does not mean we have to hate it, or put it out. We can enjoy fire, can't we? It's nice having a fire, it keeps the room warm, but we do not have to burn ourselves in it."
