Bahubali, Kailasa, Köpekli Tepe etc etc and then the huge underground tunnel cities man... and those pillars under the pyramids? My theory atm for the use of the pyramids was healing by frequency and not just any frequency but The Schumann resonance. The pillars would make it stronger, clearer.

And using them also for meditation and connecting to the source, God, name it how you will. What do you think?
