Today’s weather was gloomy, cold and wet. I have been feeling the same way for several days. “Less than crisp” would be a good way to put it. Last spring when I was sick, I continued to practice, only very very restoratively. Maybe only breathing and some very gently movement.
My reminder to myself is therefore: Unless I ‘m unconscious, I can practice yoga.

Well, I just hope you feel better, and am beaming white light to you to help speed and ease your feeling better.
