we do this repetitious shooting into the bales and long shooting to develop our form until the shooting act is almost 'thoughtless'....only then can we concentrate on the target with the intensity needed for very accurate instinctive shooting. And we respond to the target/shot scenario much like a martial artist responds to the situation faced.
when I am shooting well, and I try to get into this shooting state every time now, I see the arrow being drawn back by my hand in my peripheral vision....but once I'm at full draw, the string and hand are not visible (but they feel as if they're behind me) and my mind and body are now the arrow and where I look is where my mind is aimed, and I will leap forward at the shot to bury myself into the target. And I will not miss because I have control over my body. Kinda like feeling myself run into the target, I won't miss...
I think this is what Byron means when you 'become the arrow'...I shoot very accurately for me when I shoot this way and any target out to about 80 yards is in grave danger.
