There is "no ground" to this world. It is temporary...and can be beautiful

At present, the outer universe—earth, stones, mountains, rocks, and cliffs—seems to the perception of our senses to be permanent and stable, like the house built of reinforced concrete that we think will last for generations. In fact, there is nothing solid to it at all; it is nothing but a city of dreams.
