This ARTICLE is a great jumping off point on this topic. The article delves into the effects of sound and light on physical structure, including information from the early 1800s that made the realization that sound can effect physical matter.
If sound and light can effect physical reality, then ask yourself: how is this effecting me? Music? Noise? Sub audio? Light- and Types of light?
This is an area that concerns me greatly. It is too easy for light and sound to be used in a negative way that is disguised as normal. These new "energy saving" light bulbs are triply dangerous, yet are being forced upon the public and even being mandated by law in some areas!
Japanese scientist Dr. Masaru Emoto has done several experiments on the effects of sound and music on ice crystals. He then took his experiment to another level, using positive and negative words and studying the resulting crystalline structures.
... Our bodies are made up of vast quantities of water. Every part of our body contains water. If sound and light can effect water in experiments, then logically light and sound frequencies can also effect our bodies at the deepest level.
I do not believe that simple words written on paper have any power over the water crystals, BUT... the thoughts behind those words create emotional responses. Emotions are a physical "frequency" as well, and therefore the very act of thinking both positive and negative thoughts triggers an emotional response that causes physical changes.
Greg Braden speaks about the effects of emotion on the physical field that emanates from our hearts and the effects of the heart field. In this video, Greg shows a woman being healed of bladder cancer in minutes.
Emotions have direct effect on our physical bodies and physical reality. Think about that. This is VITAL to understand the media circus that drives our planet.
If you wish to control the population, keep them in a negative spiral, keep them from positively creating, positively influencing, positively healing... you surround them with constant negativity. You create a machine that keeps their attention on the programming, constantly bombarding them with messages to keep them addicted and programmed. You create an entire world in a box that tells them what is normal, what to think and feel, what to believe, and you brainwash them into believing that if they step away from what the box tells them, they are terrible and abnormal. Negativity breeds negativity.
This is the reason that I continuously talk about focusing on the positive emotions and staying away from the negativity that closes us off and leaves us vulnerable.
