The common idea that DNA determines so much of who we are—not only our eye or hair color, for example, but also our addictions, disorders, or susceptibility to cancer—is a misconception.
You find yourself to be more or less a victim of your heredity.
This concept “says you are less powerful than your genes.”
A person’s perception, not genetic programming, is what spurs all action in the body: It’s actually our beliefs that select our genes, that select our behavior.
The human body is comprised of 50 to 65 trillion cells. Cell functions independent of DNA and its perceptions of environmental stimuli affect DNA. This also applies the same principles to the human body as a whole, showing the power our perceptions, our beliefs, have over DNA.
The following is a simplistic summary : 5-Step Explanation
1. The cell is like a human body and it functions without DNA
The cell is like a human body. It is capable of respiration, digestion, reproduction, and other life functions. The nucleus, which contains the genes, has traditionally been viewed as the control center—the brain of the cell.
Yet, when the nucleus is removed, the cell continues with all of its life functions and it can still recognize toxins and nutrients. It appears the nucleus—and the DNA it contains—does not control the cell.
2. DNA is controlled by the environment
Environmental stimuli that come into contact with the cell membrane are perceived by receptor proteins in the membrane. This sets off a chain reaction of proteins passing on what could be described as messages to other proteins, motivating action in the cell.
DNA is coated in a protective sleeve of protein. The environmental signals act on that protein, causing it to open up and to select certain genes for use—genes specifically needed to react to the current environment.
If there are no perceptions, the DNA is inactive.
Genes can’t turn themselves on or off … they can’t control themselves. If a cell is cut off from any environmental stimuli, it doesn’t do anything. Life is due to how the cell responds to the environment.
3. Perception of the environment is not necessarily the reality of the environment
In a 1988 study done by John Cairns, published in the journal Nature titled “The Origin of Mutants,” he showed that mutations in DNA were not random, but happened in a predetermined way in response to environmental stresses.
In every one of your cells, you have genes whose function it is to rewrite and adapt genes as necessary. In a chart illustrating Cairns findings in the journal, environmental signals were shown to be separate from the organism’s perception of environmental signals.
A being’s perception of the environment acts as a filter between the reality of the environment and the biological reaction to it.
Perception rewrites genes!
4. Human beliefs, choosing to perceive a positive or negative environment
Just as a cell has receptor proteins to perceive the environment outside the cell membrane, humans have the five senses.
These are what help a person determine which genes need to be activated for a given situation.
The genes are like programs on a computer disk. These programs can be divided into two classes: the first relates to growth, or reproduction; the second relates to protection.
When a cell encounters nutrients, the growth genes are activated and used. When a cell encounters toxins, the protection genes are activated and used.
When a human being encounters love, the growth genes are activated. When a human being encounters fear, the protection genes are activated.
A person may perceive a negative environment where there is actually a supportive or positive environment. When this negative perception activates the protection genes, the body’s response is the programmed “fight or flight.”
5. ‘Fight or Flight’
Blood flow is directed away from the vital organs to the limbs, which are used for fighting and running. The immune system becomes of lesser importance. If you picture the responses we once needed for running from a lion, for example, the legs would have been infinitely more important in that immediate situation than the immune system. Thus, the body favors the legs and neglects the immune system.
So, when a person perceives a negative environment, the body tends to neglect the immune system and vital organs. Stress also makes us less intelligent, less clear-minded. The part of the brain related to reflexes is given more prominence in fight or flight mode than the part related to memory and other mental functions.
When a person perceives a loving environment, the body activates growth genes and nurtures the body.
Beliefs act as a filter between the real environment and your biology. Thus, people have the power to change their biology.
It is important to keep a clear perception because otherwise you won’t develop the right things biologically for the real environment around you.
