energy and Qi

These seem very related, yet at times one in the same.  Energy runs through us and has a certain rhythm and force.  Qi helps to moves this energy, but may also BE this energy that keeps things going.  To me, you can feel energy from people and the heat it can produce.  Some people are very aware and are able to see other people's energy around them.  There is a certain movement that may be felt in a room or inside ourselves and Qi helps to keep this movement flowing.
