Here's how I'd describe it. And I'm typing as slow as I can.[8D]

Hold your arm straight out to the side, palm down with your fingers straight and the thumb extended straight out from the hand. The inside bend of your elbow should be perpendicular to the floor. Now, keeping the elbow and upper arm still, rotate the wrist so that your thumb is pointing up at a 45 degree angle.

Now, keeping that inside bend of your elbow perpendicular to the floor, unlock your elbow. Relax your fingers and thumb. That is the exact position you want. The bow will fit in the pocket between your thumb and fingers, with the center of the grip to the thumb side of the lifeline in your palm. The index and middle fingers will wind up wrapped around the front of the grip, the ring and pinky fingers will be completely away from the grip. They could even curl up into the palm, alongside the bow's handle if you wanted, but it's better to leave them relaxed.

Don't make the mistake of trying to hold your fingers straight out, like you see so many shooters doing. They do this so they won't grab thehandle during the shot, but it'snot a good thing. It does nothing but add muscle tension into your hand and forearm, making it much easier to torque the bow.

The key thing to remember is keeping the hand relaxed. Before the shot, during the shot and after the shot, until you seethe arrow hit the target.
