Grey Jedi

Is there a source that this 'code' came from? Or is it just a fan-created credo. Because it seems to have no flow and to contradict itself. Id like to read the source material if it exists. Qui gon followed the living force by the way. He practiced balance in ones present moment and following the will of the force instinctively: not dwelling on the future or the past but letting one's connection to the force carry him/her like a river. This often caused him to clash with the Council, as they, being more traditional, saw the force as a tapestry that could be perceived with meditation, as Yoda demonstrated with his perception of future events. Food for thought.
