You see this goblet?
For me this glass is already broken.
I enjoy it.
I drink out of it.
It holds my water admirably, sometimes even reflecting the sun in beautiful patterns.
If I should tap it, it has a lovely ring to it.
But when I put this glass on a shelf and the wind knocks it over, or my elbow brushes it off the table and it falls to the ground and shatters, I say, 'Of course.'
When I understand that this glass is already broken, every moment with it is precious. Every moment is just as it is, and nothing need be otherwise.
