The world is black, the world is white and truth be told there is a lot more gray than either black or white. There are few absolutes in this abstract world we live in. You wouldn’t think of stealing food, but if you were starving and had no means to buy any, your thinking might change. Yin and yang are constantly revolving, evolving, one turning into another and vice versa. It is hard to keep up and one must be alert to these changes to remain in balance. It’s like walking across a tightrope over the Grand Canyon. You are fine and then a wind comes up and you have to adjust.
