What does this mean exactly?

Here is an excerpt from the linked article:

The “Schumann Resonance” chart registers our planet’s FREQUENCY (cycles per second of waves of ENERGY) and the AMPLITUDE (magnitude, range, strength of incoming FREQUENCIES).

The chart is comprised of various color waves—some vertical and some horizontal—all on a square or rectangular canvas.

When the chart shows large wide white splashes, this is indicative of huge amounts of LIGHT coming into our planet—within our galaxy as well as outside of it— which carries informational codes that re-set, regenerate, and upgrade our DNA, particularly at the mitochondria level which is the information receiving aspect of our DNA.
