Theta DNA Healing is something which is much easier to demonstraite, than explain, but here goes:
To start with, theta is a brainwave state. There are 5 known brainwave states, which you move in and out of at different times of the day depending on what you are doing. BETA is your normal waking state. ALPHA is a state of relaxation/meditation and the state you are in when you are gently waking from a long sleep. DELTA is when you are in deep sleep. GAMMA is a state of super learning, your brain is working at very high frequencies in this state. THETA is the state you are in when in REM sleep. It is also possible to reach the Theta brainwave state with very deep hypnosis.
Normally, the first thing that a Theta practitioner will address with a client is negative programming. We are all conditioned in one way or another, by the people around us, society, the media etc. We will be aware of some of our programming, however, a vast amount of it is stored in our subconscious and, therefore, we may have no idea about it whatsoever, but if it's there it WILL be having an effect on our lives. Most of us are gaining an understanding now that "like attracts like" and "your thoughts create your reality" and so you might be focusing your thoughts on positive things like love, happiness, abundance and good health, but if your subconscious is full of beliefs like "I don't deserve to be happy" "all the men in my family died of heart disease", "I'm never going to amount to anything" and so on and so on, then it doesn't really matter what you think consciously, as the conscious is only 5% of your mind.
In order to identify which particular negative beliefs a person has we use a process called muscle testing. This can be done in many different ways but the easiest way for someone to test themselves is as follows:
Make sure you are well hydrated
Stand facing north with your feet forward, about hip width appart, and let your knees bend slightly
Make a statement (either out loud or in your head), start with something factual to make sure you are testing properly eg. "I am a man". If you say something that is true (as far as your subconscious is concerned) then you should feel yourself lean forward, if it's untrue you will lean backwards. If you try a few times and find yourself always going forward then you could be dehydrated or out of alignment.
Once negative beliefs are found then the practitioner is able to witness them being removed and replaced with the most appropriate positive belief by the creator. At times it is necessary to dig deeper and even go into past lives to get to the root of the belief. When the beliefs that are creating the particular problem are removed then healing can take place. There are many different ways of healing with Theta. Energy always comes from the Creator. Damaged DNA can be pulled out and replaced, healing can be sent to a baby in the womb, trauma from this life and past lives can be removed and replaced with unconditional love energy, the list goes on and on.
