"Each person is at each moment capable of remembering all that has ever happened to him and of perceiving everything that is happening everywhere in the universe.

Postscript. My apologies for the poor quality of this image, but it was captured with a shivering cold hand tapping on an even colder iPhone while out on my morning walk with my wife (these now routine walks have been a very generous "gift" of our pandemic-ridden times). I had a thought to run back into the house to get one of my "real" cameras, but my brain and legs were colder still and simply refused to budge. Searching for otherworldly vistas in ice forms is one of my favorite pastimes in the winter, but I've had precious few days in which to do so (as yet, in northern VA). While work week constraints prevent me from truly indulging myself, the promise of some continued cold weather has me eagerly looking forward to continuing my search for "otherworldly vistas" this weekend!
