Things which are truly treasured usually have a low monetary value. Even if they are highly priced, their preciousness may have nothing to do with how expensive they were. Treasures become precious because of the memories wrapped in their delicate folds. Sometimes the memory is of a tender moment, an exuberant triumph or that of a precipitous milestone reached without fan-fare but with a quiet and terrible struggle.
You are often unable to explain to another, why your treasures are precious to you. To do that, you’d have to quantify and measure the exact structure of the emotional component that makes the treasure worth treasuring. To break down a complex, composite edifice of an emotional experience into is constituent parts is well neigh impossible for almost all of us.
This is why you have secret chambers in your heart. In those chambers, you hide your treasures. You don’t want to be questioned about them. You know you can never explain to another why something (or someone) is as precious to you as it is.
When you fling open the doors of the secret chambers to someone, you do it because that someone is the biggest treasure of all. They are the one for whom you collected all your treasures over the years. You know they will understand what those treasures mean to you- and why. You know those things would be precious to them as well.
