Huddled against the cold, the bitter winds that blow stands the one who is warm with their knowledge of the Dao and its ways. There will be freezing cold days where the wind bites through your clothes and latches on to your soul. Days so cold you wonder if you will ever feel warmth again. But the one who is wise also knows that warmer days are coming. That is yin and the yang. The warm days when one can walk into the tides of the ocean and be refreshed from the burning heat. To know that neither extreme will last is to know the Dao intimately and profit from it.
