This energy is difficult to describe or define, but basically it is a calm confidence that carries within. It comes from deep in our spirit and is sensed by others in different ways.
Some people will feel intimidated or uneasy; others will feel that you are dangerous and that they shouldn't cross you.
To most people, it is simply a feeling that they get about you, but they can't explain it.
Then they see you as someone to be respected, someone who knows how to carry himself in such as way that he gives off the aura of power and strength.
This is the true energy - the aura of power.
You may not sense it in yourself, but others will.
Stay on that path and I guarantee you that at one time or another, someone will mention this to you.
