As a Jedi Master I am asked all the time, what is the Force? It is called by many names; God, Karma, the Powers that be, the Universe. Whatever you choose to call it, it is all the same thing.
It guides us, motivates us to action, encourages us, shapes us, and helps us from one moment to the next.
It speaks to everyone, you just have to quiet your mind enough to listen. You will know what it says to you, you will feel it deep inside of your soul.
It is not as complicated as one thinks at all. It is very simple. That is the Force.
