To the untrained eye the physics of manual muscle testing appears straight forward. It involves applying light pressure to chosen muscles which will either show a strength or weakness according to the question asked.
You can think of your big muscles a being 100 watt light bulbs. Your mind can only turn the bulb off or on making 100 watts of bright light. However, the catch is that your subconscious controls the dimmer switch. Therefore no matter how many watts the bulb is, if the subconscious dimmer switch has turned down the power to your bulb, when your mind (conscious) switches the bulb on you only have a dim light.
We can have ‘dimmer switches’ in every area of our life, including our genes that act like auto-fails switches that keep holding us back to achieving health, wealth and happiness. Muscle testing helps us to identify and change the action of these dimmer switches to achieve the goal you want.
