A large component of the energizing effect of broadcasts is synchronization. Part of this synchronization effect is physical and part of it is supernatural (nonphysical, extradimentional). People in general like to feel a part of the collective. Broadcasts allow each individual to feel a part of the collective, and to feed of the energies of the collective. In broadcasts, there are many flavors of the collective energies. Some people listen to broadcasts by democrats, some by republicans, emigrants listen to broadcasts from their countries in their languages, blacks are listening to the black-oriented stations, religious people tune to religious broadcasts.
Most of my life I was tuning to and feeding of energies of alternative thought. In Russia it was Radio Liberty and Radio Echo of Moscow (an alternative thought broadcast). In America I continued listening to these favorites of mine and added a bit of NPR public radio (most liberal of radios), Dr. Laura, Car Talk, later I added Coast to Coast AM and with emergence of YouTube broadcasts I switched to channeled messages of aliens via YouTube. Bashar, again was most influential on me.
I also found that the energizing effects of broadcasts are not fully harmless. First, and most importantly, they brainwash people. They imprint much on conscious and subconscious level. In many ways you are what people listen to.
Second, the energy which they provide is not free. It is normally taken from persons future. Say, a person listens to broadcasts and does more work. After a while the person becomes exhausted and can not get this energy anymore. This energizing is very much like other drugs. I observed very similar effects from nicotine and alcohol. They are also very energizing, but also take a tall from persons future energy. Listening to broadcasts, smoking and alcohol allow a person to take the energy from reserves and this way to deplete the reserves. This helps productivity at work but brings illnesses.
Especially damaging are negative news. They are also energizing, they also help people to feel luckier than people who suffered from negative events, but they poison the mind and open it to negative supernatural (transdimensional) influences.
Another negative effect is distraction. Listening to broadcasts distracts workers from what they do, they think less about the work and contribute less of their own energy and thinking to the overall process. This is an unhealthy situation. Therefore in my work, I rarely listen to broadcasts, unless of course, listening is my priority and the work is secondary.
