A human soul is like a glass vase. So fragile, so easy to break. Just one touch, and it can shatter into a thousand shards. So many pieces that not even a lifetime would be enough turns of the clock to meld it all back together.
So instead of being glass...
Why don't we turn our souls into diamonds instead?
After all, diamonds are one of the strongest materials to be found in nature that can be shaped into something beautiful.
Who wants to be seen as glass that can be pulverized with the slightest of pressure, when instead you can be viewed as one of the most durable and gorgeous souls in the world?
