Pixie Investigation With Mr. Erwin Saunders.

[Mystic Wanderer]

I remember watching a show by Michael Tellinger when I was subscribed to GAIA t.v.  He talked about how stones absorb energy from the earth and transmit it above ground. The Ancients arranged the rocks in a certain pattern for a reason. Apparently, they create a certain tone or energy that was needed for some reason back then. They were much more advanced in that type of thing than we are today. 
The crop circles/mazes probably produce a similar effect on the human body when walked along a certain path.
