Yesterday morning, I took my 6am walk in bright light of the harvest moon. I followed this by a 10 minute qigong practice looking west, my face bathed in the moon's light. I generally squeeze in a morning qigong practice a couple of times a week. I usually I stand in the yard facing east, looking at the rising sun. Friday morning, though, I walked around to the west side of the house so my face would be bathed in the light of the setting moon. Splendid.
I probably won't want to continue my morning walks for very much longer. Soon it will be either too dark or too cold at 6am. I'll probably switch back to taking my walks during my lunch break.
