"I am not a man of words. But I respect the power of words, for that is what transformed me. The words of the Sith Code. Others had heard them, contemplated them, and so on. But I understood them, and they changed me. For what was I before I heard those words? Nothing."
―Darth Bane, Dark Lord of the Sith[src]
The Code of the Sith, known as Qotsisajak in Sith language, was the mantra that reinforced the core beliefs of the Sith Order. It was considered the dark side counterpart to the Jedi Code, and was first authored on the planet Korriban in 6,900 BBY by the Jedi heretic Sorzus Syn. The code remained remarkably unchanged through the millennia, as the Sith Lord Darth Bane still taught the words of Sorzus Syn when he began rebuilding the Sith Order around 1,000 BBY, after the Seventh Battle of Ruusan.

IN ENGLISH

Peace is a lie, there is only passion.

Through power, I gain victory.
Through victory, my chains are broken.
The Force shall free me.
