Oneness

Oneness was the state of union with the Force. While under normal circumstances this could only be achieved after a Force-sensitive had died and passed into the Netherworld of the Force, this was not always the case. In some select circumstances living individuals managed to become an extension of the Force. They essentially became nothing more than an extension (a tool) of the Force, and were at a perfect calm.

Some Force-sensitives who achieved this include:


 * Anakin Solo: On the Myrkr mission against the Yuuzhan Vong.
 * Ganner Rhysode: In captivity on Coruscant he managed to single-handedly hold off and kill several thousand Yuuzhan Vong warriors before finally collapsing the roof of the Senate hall to wipe out the rest of the Yuuzhan Vong forces and their battle creatures.
 * Luke Skywalker (possibly): On the way to confront Shimrra he slew countless Yuuzhan Vong as well as many Slayers in a state that was described by his nephew Jacen as a maelstrom of the Force.
 * Jacen Solo: In the final battle of the Yuuzhan Vong War, Jacen achieved a total oneness with the Force, becoming a being of glowing light. He reversed Onimi's deformities which removed his protections to his own toxins. When he returned to his normal form, Jacen did not perceive it possible for him to ever achieve oneness again.

Behind the scenes
It could be argued that it is in fact easy to become one with the Force, as in the Revenge of the Sith novel, it is stated that whenever a great Jedi enters battle, he or she becomes unified with Ashla. However, it is possible that there are two kinds of oneness, basic and advanced.
