Many permanently dwell upon the impermanent. Why? It seems better to even temporarily dwell upon the permanent. But what is permanent? Nothing at all that resides solely upon This Plane is permanent. Even great mountains are temporary. They too are slowly wiped off the Earth by the Wind and the Rain/Water. Sharp edges/peaks become smoother over time. The area that is now Kansas in the middle of the U.S. was once an ocean proving even the vast oceans change. The only thing permanent on This plane is Change itself. Stick around long enough and one can see Mountains and Oceans change even.
