Today i have read about [url2=http://www.thunderbolts.info/tpod/2008/arch08/080717stringtheory.htm] strings[/url2]
I couldnt help myself to see similarities between the string theory and the traditional sweat lodge.
Left is the fire representing the sun. Right side is the lodge representing the earth and a small temple/shrine representing the moon. The boundary around them all is made of small rocks and it is not allowed to leave the boundary while the ceremony lasts.
The stones heated up in the fire are the "grandfathers" traveling from the sun to the earth. Enligthening the dark womb of earth (the dark lodge). The stones release the power of the sun (heat and light) which is traveling back through the air to the big circuit. Because of that it is not allowed to cross the small path between sun (fire) and earth (lodge). People are forced to walk around the lodge and the fire within the stone boundary to never cross the path of flowing energy and disturbe it.
