The way of the water
What happens when you sink into the Yin? Does it swallow you? This is the fear of the feminine and the quality of water. What does the water do? It holds you while you float. It carries you. This is a big thing and it has to be achieved. Because the water won't carry you, it won't hold you, if you don't sink into it, if you don't give into it. Most of us never reach that point. You need to let go, so that the Yin can take over and carry you.
