A Jedi was a member of the Jedi Order, who studied, served and used the mystical energies of the Force; usually, the light side of the Force. The weapon of the Jedi was the lightsaber, a weapon with a blade made of pure energy. The Jedi fought for peace and justice in the Galactic Republic, usually against their mortal enemies, the Sith and Dark Jedi, who studied the dark side of the Force.
Path of the Jedi 
Edit
- "You have chosen the lonely path. The Jedi teach denial of self. That is their weakness. No sentient can long abide that."
- ―Saes Rrogon, Jedi-turned-Sith Lord[src]
Becoming a Jedi required the most profound commitment and astute mind; the life of a Jedi was one of sacrifice. To hinder transgression, those who showed an aptitude for the Force were taken directly from birth (or soon afterward) to train in the Jedi Temple headquarters on Coruscant or at smaller Jedi Enclaves as Padawans. From the beginning of their training, a Jedi was expected to adhere to a strict Code that included concepts such as rational thought, patience, and benevolence. Dark emotions such as hate, anger, and fear were thought to be destructive, leading down the path to the dark side, so the Jedi were taught to purge such feelings.
