Which direction is tilt

So New to the program, and been watch a lot of video and still confused about tilt,

Is tilt when you tilt toward the ball? so your arms (if straight out in front of you ,are pointing towards the ball, then you just turn your shoulder 90 degrees around your spin?

The KFC tilt video mentions tilting toward the ball, but other video mention tilting towards the target.

For the drill if I put my head against the wall and turn my left shoulder down. that is great and do I just do that after I am setup at the ball???? if so where does tilt come in, unless it is tilting towards the ball.

Tom do you have a clearer video of this?
