NOTE: Taken from a conversation on Jedi Church (the Original) where Connor responded to a conversation between two separate individuals.
(REDACTED)'s point is, succinctly, that the Code is what defines the Jedi because it is the lens by which Jedi view the Force and therefore how they interpret their own morality and therefore how they choose to act. Meditation on the Force, alone, is not enough to justify being anything except a person who meditates on and believes in the Force. Also, because the Force is morally ambivalent (it is, I promise), the Jedi would do well not to simply follow the Will of the Force because that could lead to exactly what happened to Anakin. He gave into the Dark Side (which is equally a part of the Force), and he killed hundreds or perhaps thousands of people during the Empire's rule.
It is naive to believe that Force is not both Dark and Light (and neither and both).
If I am reading your translations correctly, (REDACTED 2), you are saying that the films show that meditation on the Force and self-reflection are, inherently, a guide for the Jedi. Right Action is a direct result of internal meditation and reflection.
In most traditions, you would be right. But, the Jedi do not choose to view it this way. Jedi, in this community, oftentimes recognize that self-reflection and meditation do NOT lead to the Light side. Rather, they lead to becoming a more authentic version of yourself. This could be a Lightsider, a Darksider, or something else entirely (paging the Grey and the Shadow).
Instead, we believe that the CODE itself is the arbiter of our morality. It helps us to focus and reach a higher plane of behavior and thought.
Even those who do not accept the code oftentimes will come up with a morality all their own to help guide them.
In Buddhism, this is also true. If you'll notice, behaviors and actions are covered in the 8-fold path. They provide GUIDES on how to interact with the world, and this is like their version of a Code.
