Establish the Plane Line by putting two shafts on the ground a few inches apart and aligned to the Target. Then stick another in the ground behind you to establish the Plane Angle. Finally, position a water bottle just in front and to the right of the Ball (which is located between the two shafts on the ground). This is your visual 'Gateway to Golfing Perfection' through which the Arc of Approach -- the curved path of the Clubhead Blur through Impact -- must pass. Your mission is to swing Through the Ball -- and through this 'mine field' -- without disturbing any of the deliberately placed obstructions.

Thats a great explanation. Still I do not fully understand the positioning of the two first shafts and how that "Gateway" appears. I'd be very grateful if someone would be able to provide a link to a photo of the entire setup.
