We are like children building a sandcastle. We embellish it with beautiful shells, bits of driftwood, and pieces of coloured glass. The castle is ours, off-limits to others. Yet despite all our attachment, we know that the tide will inevitably come in and sweep the sandcastle away. The trick is to enjoy it fully but without clinging, and when the time comes, let it dissolve back into the sea.
