Events on earth such as thunderstorms and in outer space such as intense solar activity constantly produce extremely low frequency electromagnetic waves below 40 Hertz. Did you know that lightning strikes somewhere around the globe several times every second of the day? This produces a constant supply of natural frequencies that circle the earth, trapped between the earth’s surface and ionosphere, energy available to Philip Stein.


In 1952 German physicist Winfried Otto Schumann proposed the existence of natural electromagnetic waves surrounding our planet. Eight years later, in Germany biologist Ruetger Wever used a variety of experiments to show that these Schumann Resonances can positively influence health, performance and overall wellbeing of humans. It wasn’t until the late 70’s that these Schumann frequencies were detected from a balloon by a Japanese research team.
