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