From what I understand, the Jedi Code has been corrupted. The original code followed a structure of "X, yet Y", but was updated 'to avoid confusion' to "There is no X, there is Y". I feel that this has greatly crippled the Order's teachings. Tell me, which makes more sense to you?
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
or
Emotion, yet peace
Ignorance, yet knowledge
Passion, yet serenity
Chaos, yet harmony
Death, yet The Force
I prefer the latter. It has much broader interpretations, true, but in a positive way. It acknowledges that these aspects exist, but it is possible to stay strong within them... to have peace amid emotion, serenity within passion, and so forth. "Ignorance, yet knowledge" is perhaps the most important, as it suggests that you can learn something valuable in the most unlikely and "ignorant" of sources; Obi-Wan demonstrated this when he sought out Rex in "Attack of the Clones".
