The Force is a metaphysical, binding, and ubiquitous power that held enormous importance for both the Jedi and Sith Orders. Known as "the Way" in ancient times, the Force is viewed in many different aspects, including, but are not limited to, the light side, the dark side, the Unifying Force, and the Living Force. The first two aspects were concerned with the moral compass of the Force, as manifested by the conduct and emotions of living creatures who were themselves part of the fabric of the Force. The light side of the Force is the facet aligned with compassion, selflessness, self-knowledge and enlightenment, healing, mercy and benevolence, while the dark side of the Force is the element aligned with hatred, fear, covetousness, anger, aggression, jealousy and malevolence. The latter two aspects are defined by prominent Jedi philosophies: The Unifying Force essentially embraces space and time in its entirety while the Living Force deals with the energy of living things. Though the Force is categorized in this way, there are 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 forms that used it, and drew energy from their emotions.
Some beings, particularly the Sith, believe that the Dark Side of the Force was more powerful than the light, though it is possible that the Dark Side was just more tempting to those who use it (or desired to use it). Others think of the Force as an entity capable of intelligent thought, almost as a sort of deity.
Though the Force is thought to flow through every living thing, its power can only be harnessed by beings described as "Force-sensitive." This Force-sensitivity is correlated with, and sometimes attributed to, a high count of internal microorganisms called midi-chlorians that are found in a Force-sensitive's blood: the higher the count, the greater the being's potential Force ability, though there are some exceptions to this rule. Force-sensitive beings are 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".
(see:) Over the Centuries, many Force- Sensitive Individuals have organised into groups of force users. Some of these Groups are created as a subdepartment of an existing Organisation. Others are associated with a particular organisation through the circumstances of history. There are also Force Users who hold no allegiance to any of the organisations listed below out of a desire to remain independent.
