Telsa had the answers long long ago:
Alpha waves in the human brain are between 6 and 8 hertz. The wave frequency of the human cavity resonates between 6 and 8 hertz. All biological systems operate in the same frequency range. The human brainโs alpha waves function in this range and the electrical resonance of the earth is between 6 and 8 hertz. Thus, our entire biological system โ the brain and the earth itself โ work on the same frequencies. If we can control that resonate system electronically, we can directly control the entire mental system of humankind.
