I am writing about more than sunlight, you know... although the swift-passing window of the Winter Day is no small matter either. These are the shortest days. And for many they are filled with hectic activity. For others they are cold and barren desert of Depression. Lao Tzu writes: "Movement overcomes cold."
Translating this into one's own practice means that during darkest days of Winter, instead of hiding under a comforter and napping all day, one should keep active. Do many things even if you feel like sitting still - this is how one makes it through the worst Winters, even the most terrible Winters of the mind.
The converse also holds true. During the hot days of Summer, or even the most hectic and anxious times of any season, one should seek to still the mind and body. "Keeping still overcomes heat."
The words hold not just literal truth for the thermostat of the human body. Properly applied, the words can govern our moods. They put into the hands the reigns of the intellect. Anxiety and panic are also ruled by the still Player.
Well, now I've got to go fight off the cold/flu I've had for more than a week and start following this advice! :-)
