If you accept negative information into your energy field it is known that it will have a negative affect on your health and the functioning of your body.
The question is how do we reject negative information and hold onto a positive field of energy that is healthy when we are continually impacted with negative thoughts from acquantences, family expectations, angry bosses, or small perspective social issues?
The only real answer is to raise our vibration to a higher level. Choose to stay in gratitude, appreciation, love and admiration. Love is the light that dispatches the darkness of fear and anger. Fear and anger can not touch you as long as you stay in grace.
