Check this out.... a series of video clips about crop circles, sacred geometry....

You Tube Videos - Crop Circles

I'm really facinated by crop circles. Anything to do with circles drawns me in.

The theory the guy in the clips presents about the water was kind of spooky so part of me says 'woooh'.

As I listen to him talk about the 'energy' that is read or captured in the spaces.... I hear myself say, 'yes... that's spirit... those are spirits.' That's what being spirit is like in my mind... my spirit in me... my force of energy.....my link to the source of our source....the highest energy, God.

(I guess that's fits with what you mentioned about meta-physics. Not so familiar with that term.)

Anyways.... even the impression of how the energy/spirits sound..... so soft as to be inadable to the human ear. Those were the sounds recorded from inside the crop circles. Pretty awesome.

I enjoyed watching the clips, thought others might too.

Here's a clip of a recent circle in Canada
