Today the mountain that I live on is covered in mist and periodically it rains. A picture of this would just be all white and not really convey the beauty of the mountains in any weather. So let me quote Carl Sandberg
The fog
"The fog comes n on little cat feet
Sits silently on its haunches
and moves on."
How beautiful and how simple a way to describe the total silent envelope the fog raps around you.
Have a foggy external day with a clear inner sense of what you are doing!
