Yes, we are beings who vibrate at various frequencies, some lower than others, some healthier to the organic matter that makes up the body than others.

The best, healthiest energy to vibrate at is that of calm assurance. The body settles into homeostasis and every fiber of the body is put in the most ideal set of conditions to rest, relax, and heal.

When fear and anxiety are present, tensions created by our electrical systems (over-firing) cause the degeneration (sped up aging) of cells and, ultimately, diseases of mind and body.
