It really seems that there are many different ideas of what a Jedi should be, know and do. No wonder there are so many different groups of Jedi out there.
My personal opinion is that a Jedi should be trained to be:
If they aren’t already, they need to work out for themselves who they are and what they want out of life. They need to establish this firmly so that they can move forward with discipline and dedication.
An understanding that a person is connected to something greater is essential because that leads towards the development of things such as ethics, morality, service and responsibility for one’s actions.
One of the ways that a Jedi Knight or Master (If you use ranking systems) impacts the world is by training others to be Jedi. Knowing how to be an effective leader is necessary in order to motivate students and keep the group stable. It is also required for self development because the first person that a leader must lead is themselves. Leadership skills include ethics, service, influence, communication, conflict resolution, planning/visioning and teamwork.
The Jedi are a warrior culture and I believe that it is somewhat important to retain that culture. Training in the martial arts or military arts, properly taught, will put a person in a different mindset. When we think of the groups that the Jedi are modeled after – Samurai, Shaolin Monks, Medieval Knights – we realize that there is a commonality that put them a step above the rest of society; their close association with death. It is only through realizing that death is at an arms length away that we strip away the things that are insignificant in our lives and truly live with personal power. I believe Dale Carnagie provided this insight when it came to dealing with personal fears: If you are afraid of something, think of the worst possible scenario. If you’re afraid of flying; think that it might crash. Expect it to crash and prepare for it. Because you are expecting the worse you’ll have a better time because you’ve given yourself over to dying and the little bumps and shakes that the plane makes will be insignificant. In comparison with that, how insignificant is it to give a public speach? Why do we tear ourselves up and give ourselves ulcers over things like talking in front of groups – for fear of embarassment? How trivial! The warrior lives as if each day could be the last. So priorities are set in place and the big things taken care of immediately. Life is more rich, more full. That type of living is what being a Jedi is about.
