While you want the ball to travel to the target and ideally set your stance up so that the shoulders, hips, knees, and feet are parallel with the target line, there is another target - the actual ball itself.

To hit this ball with power and accuracy, you need to deliver the clubhead down and across the target line as per the red direction of the hit line above.

This is also called the A to B Line, with the A being the clubhead at the top of the backswing and B being the ball.
