Force spirit

"All energy from the Living Force, from all things that have ever lived, feeds into the Cosmic Force, binding everything and communicating to us through the midi-chlorians. Because of this, I can speak to you now."

- The spirit of Qui-Gon Jinn, communing with Yoda

With the knowledge to retain their consciousness after death, certain beings were able to appear as Force spirits through the Force. The knowledge was open only to those who followed the light side, so the only known individuals with the ability to manifest after death were Jedi. The Force Priestesses, who dwelled on the planet said to be the origin of the midi-chlorians, taught the skill to Qui-Gon Jinn, the first known Jedi to learn the secret. His training was incomplete upon his death, however, so he could only manifest as a disembodied voice. The secret was later passed on to Obi-Wan Kenobi, Yoda, and Anakin Skywalker.
