The use of mantras and chanting to connect with a higher plane has existed in cultures all over the world dating back thousands of years, but why would people who had no contact with each other all subscribe to this practice? Could there be certain frequencies that connect us with greater--perhaps extraterrestrial--forces? Researchers have found that dozens of megalithic sites stretching across the globe--like the prehistoric Newgrange monument in Ireland, the chiseled labyrinths underneath the island of Malta, and the giant temple complex of Angkor Wat in Cambodia--were all designed to emanate the exact same frequency. The planets in our solar system each give off a distinct sound, and certain places on Earth, like Taos, New Mexico, have been found to produce a hum from an unknown source. Might the best evidence of alien intervention on Earth be found not with our eyes... but with our ears?
