Quote: Change is Constant

"The present is just a wall between yesterday and today. If you go to the beach, you see water and you see sand.  There looks like there is a line between them.  But the line is not a third thing.  There is only water, and there is only sand.  Similarly, all moments in time are either in the past or in the future, which is to say the present does not exist."
