The Jedi were most likely based on one of the real world's eastern religious traditions. Much of their symbolism has parallels in certain branches of Buddhism.
Trivia: Contrary to popular mythology, there is no officially-recognised Jedi religion. An Internet prank at the time of the 2001 UK Census informed citizens that if enough Census forms were received giving 'Jedi' as the religion, it would have to be recognised by the state. However, this was never the case, and the Jedi 'religion' remains entirely fictitious.
Jedi are keepers of the peace, which means keeping the Force in balance. Before becoming a Master Jedi, they are trained as Padawan Learners, and then are taken as an apprentice by another Jedi. They learn from a young age and have rules to abide by.

Most jedis eventually becomes politicians, CEOs, marketers, lawyers & PR consultants.
The Jedi are gifted with an ability to manipulate objects and people around them by using the Force: the force is a life energy. The Young jedi usually no more than one year old are taken to the Jedi temple to be trained in the arts of the force.
For the first several years of their lives the youglings are raised in a creche, later when around the age of thirteen years they are put through initiate triels this is to ditermine those who can be taught and those who can not.
when an initiate is chosen they will spend the next ten to twenty years traing under their Jedi Master with the new title of Padawan.
When the Padawan is deemd worthy to face the Knight triels they will do so and those who pass become Jedi Knights, after several years the shall be expected to take a padawan of their own they then become a master. if the Jedi is worthy enough and has proven him/her self they may become Council Members this is a hard titel to earn and can take the better part of seventy years to earn it.
Not all Jedi become Padawans some are trained instead to be Healers (Doctors) grow food for the poor or become bodygaurds.
There is no emotion; there is peace.
There is no ignorance; there is knowledge.
There is no passion; there is serenity.
There is no death; there is the Force.
"No, shut up, he's a jedi."
The Jedis form an Order of The Jedi. Young gifted children are taken into the Temple, where their training in the ways of the Froce begins. younglings are prepared to the role of Padawans. A Padawan is the student of the Force assigned to a mature Jedi Knight, which from now on is the Padawan's Master. The Padawan follows his master everywhere, and helps him on his tasks. This builds a strong relationship beetween the Master and the Student. During the journeys with his Master the Padawan takes several ritual tests - The test of courage, proving the Padawan can control his fear and act to the will of the Force even under stressful conditions, another tast that proves he can beat any opponent in combat, and the mst difficult - the test of Spirit, allowing the Padawan to look into himself and confront the worst of his own fears. Even after these test a Padawan is not automatically promoted to a Knight - the final decision is always in the hands of the Jedi Council. The Master can report whether he liked or disliked the way his young Apperentice passed through the tests, but it is the Council that decides. After the Council promotes a Padawan to a knight, the head of the council cuts the Padawan's hair (each padawan has a tail of hair behind his left ear). A Jedi knight then takes direct orders from the counsil and is trusted to perform missions. A Jedi Knight is a true Jedi. Most jedis met in the Galaxy are Jedi Knights.
The council may grant a Jedi knight another rank - the rank of a Jedi Master. This is done in respect to whatever the Jedi did in his career, or the promotion is simply proposed by the Force itself (or so the coucil says). A Jedi Master automatically becomes the member of the Jedi Council and from this day on his decicions affect the whole Order.
