Best trading book ever. I had to read it many, many times before I started to understand what he was talking about.
"The long and short are in your hands,
Above and below exist because they each do,
What you want and what you say should be the same...
Neither future nor past can exist alone."
And my favorite:
"Heaven and earth are like a pair of bellows;
they are empty, and yet they can never be exhausted".
