The Schumann Resonance:
All vibrating things in this world have their own, "natural" frequency which they are most comfortable with. When a thing is subjected to an external force that makes it vibrate at a frequency it vibes with the most, the thing responds joyfully, by vibrating at the maximum amplitude (energy). This phenomenon manifests throughout the universe. This natural frequency of that thing or body is known as its "resonating" or "resonant" frequency, and the phenomenon is known as "Resonance".

For those of you who have watched or read The Secret, this will ring familiar. This app aims to attune you to this universal frequency and let the body's cellular vibrations become aligned to the stationary wave in the environment. It is much like the two leaves of a bascule bridge aligning with each other. That is precisely the time when the consciousness (and aura) gets the chance to expand, go beyond the limitations of the body and spread itself into the vast expanse of the universe beyond. And this is an ineffable experience.

When two vibrating systems are in resonance with each other, a rise in amplitude in the waves takes place. In our case, the brain and the global electric circuit resonance leads to a rise in amplitude in the waves dancing in our brain. Rise in amplitude causes a rise in our consciousness energy. Logically, at some point, damping forces set in, which prevent the amplitude to go beyond a certain level. Which is in our best interest too, for this damping protects us from an experience which we may not be prepared for. The trick, therefore, is to keep reaching and touching this amplitude, and gradually increasing its levels.
