Counter to millennia of Jedi teachings, the followers of Potentium claimed that there was no inherent evil in viewing the Force. They claimed that what others called the light side was actually just the Force itself, which is inherently good. This was backed up by the fact that Ashla, the ancient name of the Force, came later to describe the light side. What others therefore called the dark side was a perversion of the Force, twisted by those who used it. Believers of Potentium said that the potential for light and dark sides resided in the user, not the Force itself. They also thought that the Jedi Masters refused to believe in the Potentium view because it would mean the Jedi were not needed to fight evil, for evil would not exist. And since there was no dark side, there were no dark side actions or Force techniques; in effect any action, good or evil, could be performed without risk as long as the intent was not evil. Some Jedi theorized that the Potentium may have originated as a Sith scheme to subvert Jedi teachings.
About a century before the Battle of Naboo, the followers of Potentium were expelled from the Jedi Order, parallel to the Jedi Order's treatment of Gray Jedi as "misguided." Yoda and the rest of the Jedi High Council did not consider them Dark Jedi, but they said it was the duty of the Jedi to use the Force to protect others, not study its absolute limits. The Council said that testing the Force to its limits would lead to the dark side.
It should be noted that some followers of the Potentium still attempted to avoid the dark side. They, however, saw the dark side as something within themselves to be avoided, not something in the Force. They reasoned that if the Force was the energy that flows through all life, the dark side simply came from the corruption of humanity. They felt that if they could be perfectly moral, they could be immune to the dark side and therefore use any technique they wanted.
