In life, there are always two directions in which you may go, up or down in energy value. Therefore, the nature of all thoughts and experiences may be summarized by both addition and subtraction in the form of added or subtracted energy from your personal energy value, as is indicated by the emotional state that arises due to the thinking of a certain thought since your emotional state equals your personal energy level. The more positive your emotional state becomes, the higher in energy are the thoughts you are thinking.
Division also plays a role in defining your life experience since your present reality is of an energy value equaling the average energy value of your thoughts. The vibration of each thought helps to define your overall vibration by mixing with your preexisting vibration thereby resulting in a vibration that equals the average vibration of all prior thought.
