The Frequency Relationship

Alpha waves in the human brain are between six and eight hertz. The wave frequency of the human cavity resonates between six and eight hertz. All biological systems operate in the same frequency range. The human brain’s alpha waves function in this range and the electrical resonance of the earth is between six and eight hertz. Thus, our entire biological system - the brain and the earth itself - work on the same frequencies. If we can control that resonate system electronically, we can directly control the entire mental system of mankind.
