Jiaasjen
From Wookieepedia, the Star Wars wiki.
Jiaasjen was a theory and ideal which helped shape the Jensaarai movement. It was apparently the Sith phrase for "integrating the shadow". The basic premise of this view was that the teachings of the dark side of the Force could be integrated into the use of the light side. This is also similar to Count Dooku's belief that a perfect being could draw on light and dark side equally. Jiaasjen theory was developed by Larad Noon, one of the only survivors of the Brotherhood of the Sith who felt great guilt for his misdeeds during the Great Sith War. Noon developed the theory to rationalize his wrongdoings and to keep from going insane. Noon wrote extensively on Jiaasjen during his self-exile on the planet Susevfi until his death sometime later.
Several thousand years later during the Clone Wars, the followers of the recently deceased Nikkos Tyris led by the Female Saarai-kaar arrived on Susevfi searching for Sith teachings. Instead, they came across Noon's writings on "integrating the shadow". With no other teacher to follow, the Saarai-kaar integrated Noon's writings into the teaching of her Jensaarai followers, creating a Force cult that was neither wholly light or wholly dark in nature.
