Sand

I can well understand why children love sand

Wilhelm Wittgenstein

It is the first thing in life to slip between your fingers

And the first castle you ever own

It stretches out before you beckoning you to follow

And then begs you to stretch out  and soak up its warmth

The poet Blake suggested that within its walls we can find a universe

Today, I think that is exactly what I will do

And I will let none of it slip away

 "For You said, ' I will surely prosper you and make your descendants as the sand of the sea,
which is too great to be numbered.'"
Genesis 32:12
