Force

Definition of the Force
The Force was divided into four aspects: The light side (often referred to as "the Force"), the dark side, the Unifying Force, and the Living Force. The first two aspects were concerned with the moral compass of the Force in its various manifestations. The light side of the Force was the facet aligned with good, benevolence, and healing, while the dark side of the Force was the element aligned with fear, hatred, aggression, and malevolence. The latter two aspects were defined by prominent Jedi philosophies. The Unifying Force essentially embraced space and time in its entirety. The Living Force dealt with the energy of living things. To some Jedi, "The Force was life, and life was the Force." Though the force was categorized in this way, there were no specific abilities or powers that were only usable by a follower of a different path of the Force; the Force partially existed inside the life form that used it, and drew energy from their emotions.

Some beings, especially the Sith, believed that the dark side of the Force was more powerful than the light, though it was possible that the dark side was just more tempting to those who used it (or desired to use it). Others thought of the Force as an entity capable of intelligent thought, almost as a sort of god. Anakin Skywalker, who was believed to have been conceived by the Force itself, gave credit towards the view of the Force as a sentient entity.

Though the Force was thought to flow through every living thing, it could only be harnessed by a minority of beings described as "Force-sensitive". This Force-sensitivity was attributed to a high count of internal micro-organisms called midi-chlorians that were found in a Force-sensitive's blood: the higher the count, the greater the being's potential Force ability. Force-sensitive beings were able to tap into the Force to perform acts of great skill and agility as well as control and shape the world around them. Sometimes this ability was described as having a strong Force "aura", and it is quite probable that the two traits were connected.
