Ahh! Now it is clear.

The shadow- when the spectators made a shaft of light through. It was at this point he touched the sand where the light was.
But the light is a natural element. He asked the spectators to block the light. He was "building a stance?" or whatever -the same as having an umbrella held while U putt?
Where are the rules people when U need them? I don't think that violation was reported.

14-2/2.5 Player Positions Bag for Purpose of Providing Shade for Ball

Q. A player positions his golf bag near the teeing ground for the purpose of blocking the sunlight from the position where he tees his ball. He then makes a stroke. Is he in breach of Rule 14-2?

A. Yes. As the player was not in contact with the golf bag, he accepted protection from the elements in breach of Rule 14-2. This answer differs from that in Decision 14-2/2 as, in that case, the player was in contact with the umbrella.

While a player may not place an object or position a person for the purpose of blocking the sunlight from his ball, he may ask a person (e.g., a spectator) who is already in position not to move, so that a shadow remains over the ball, or to move, so that his shadow is not over the ball.
