Is Depression Really From a Chemical Imbalance?

I have wrote in some of my past blogs with links

that open the doors to thinking about depression in a different way. What if we have been told that there is a chemical imbalance that really does not exist? What if we have been moved into a "controlled box" way of thinking about depression? What if we were told the only help is by adding more chemicals that actually do nothing to heal or support proper balance anyway? What if taking these drugs is really nothing more than a placebo designed to make us think that they are working for us? ALWAYS REMEMBER that drugs are designed for blocking responses in the body. Sometimes this may be helpful and more times it is not. Well, it turns out that the natural health field had this problem diagnosed pretty accurately as this article shows http://beyondmeds.com/2012/01/25/chemicalimbalancemythfalls/. I suggest that you read this and look into this further.
Chinese Medicine and Native American/Toltec approaches teach us that the personal authority of a person originates or is moved into expression in the liver/gallbladder area of the body. We learn in these traditions that depression may be the "feeling" of being disconnected from our personal authority or the "feeling" of being disconnected from our heart and spirit. If you are disconnected long enough then you will possibly download information to your hard drive(brain) that reinforces this scenario. Then you may go to a doctor or shrink that tells you the problem is all in your head while being given a drug to block those receptors in the brain that have been told what to believe. However, the "depression" never originated in the brain, the non-harmonious energy flow started out else where and now is being symptomatically  treated again vs. getting to the root of the problem.
What if depression is nothing more than the "feeling" of lack? What if the cure is boosting the energy of a weary body, while correcting the energy flow of the body? The ancestral knowledge of the culture's that walked this world before us acknowledged this. Maybe it is time to turn to that ancestral knowledge to heal once again........
