The evolution of the Shumann resonance of Earth, can be looked at in exactly the same terms as we have looked at the evolution of the cohereing of the harmonics of the human brainwaves. It is appropriate the the Earthís natural Schumann resonance when first shown to doctors was mistaken for a brain wave printout.

Working with brainwaves we discovered that addiction or attention deficit were sustainably eliminated clinically when feedback cues created a harmonic series which was geometrically PHI embedded. More simply, this meant that if a harmonic series of alpha theta delta brainwaves became beautifully caddeuceus like by the ratio PHI, THEN charge was sustainable in the brain, and attention deficit and addictions disappeared.
