What do they represent? That's the question I'm coming up with, now that I'm at an advanced belt level. On the 2 new forms I've learned so far: one starts off with both hands start like I'm used to seeing (like when I'm ready for a command from my instructor), except the hands are open and as I'm about to take my first step, it's a strike to the groin area. The other form is my left hand is at my waist in a fist with my right hand covering the knuckles. I'm not real certain as to what that is, but have a couple of ideas. There is one more at my belt rank, and a few others that I've seen in more advanced levels. What I was wondering, was why so many different hand positions, and do they have any meanings?
