Our reality is such that frequencies have a much more profound effect on us than we've been previously led to believe. This reality can no longer be ignored.
As technologically advanced as we are constantly told we are these days, there are some technologies just now being presented to the public as "new" when they are not new at all but have simply been widely suppressed for decades. Things like the "new" digital neuro headbands that pulse specific electromagnetic frequencies into a person's head to "transition" his or her moods, for example.
It has also come out in recent years that frequencies can cure diseases, including cancer. Professor and researcher Anthony Holland even gave a Tedx talk on "Shattering Cancer with Resonant Frequencies" a few years back, discussing the ability to destroy cancer cells and deadly super bugs like MRSA with oscillating pulsed electrical fields… not that you probably heard about it on the nightly news or anything.
