Most Jedi embrace the Jedi Code, also sometimes referred to as the Four Jedi Truths:
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.
Sometimes the code consist of five lines, with the extra line becoming line number four:
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.
Source Material
The Jedi Code (with either four or five lines) is presented in a variety of Star Wars related source materials, including role-playing books and video games. It is considered the code of the Old Republic Jedi, embraced in the time before Palpatine became Emperor and formed the Empire. In contrast the Jedi Creed is the code of the New Republic Jedi, led by Luke Skywalker.
