Sit and Sink/Relax

My teacher pointed out to me a mistake that I have been making, but did not realise. I had thought that having a low stance would help me in relaxing and sinking my kua, but obviously, I was wrong. While I was sitting on my kua, I was not relaxing it, I was not sinking it.

So having a low stance and sitting on your kua is not enough. You must still put in that extra effort to relax your kua, and to sink it down. Otherwise, if your kua is not relaxed and sinking down, you will still not be able to use your kua to turn and direct your force properly.
