Qui-Gon Jinn

There is no emotion; there is peace.
There is no ignorance; there is knowledge.
There is no passion; there is serenity.
There is no chaos; there is harmony.
There is no death; there is the Force.
-The Jedi Code

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 headquartered on Coruscant or at smaller Jedi Enclaves. 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. Emotions such as hate, anger, and fear were thought to be destructive and lead to the dark side, so such things were banned from Jedi practice.
