“The sandstone chambers of La Maná, Ecuador gush with a sacred springwater subsequently discovered at the ancient subterranean habitation site. The La Maná springs still resonate an intense energy that has been the focus of thorough international investigation. This spring water is of such selective purity that it has been considered a technological feature of the inhabited cave. This situation is not unique, however, but part of a global system of subterranean sites with sacred rivers encircling the Orion pyramids of Giza, Egypt including Tlacote in Mexico, Iyacyecuj Cave in Peru and China’s Huashan Caves.”, referenced here: http://www.humanresonance.org/water.html .
