My plane back to the UK was delayed a while, which gave me a window to head up to the Mayan Pyramid overlooking Teplotzlan.

You can see exactly why they built it here - a horseshoe-shaped range of mountains, that would naturally be amplifying the Torus for the whole area. In fact you can see in the distance the white building, the Cathedral, which would be right at the centre of the energy field - harvesting energy, and controlling it. Through this approach, I would say the Mayan pyramid would be overlaying its own frequency for the whole valley, and way off into central Mexico. They knew exactly what they were doing!
