this was the facet of The Force which focused on the future and its bearing on a Jedi's place in the present. Those Jedi who studied the Unifying Force understood that the future was constantly in motion, but sought to understand this motion and develop an understanding of their place within achieving the highest of ideals. This facet complimented the Living Force, which connected a Jedi Knight to the living beings which surrounded him, and the Physical Force, which allowed a Jedi to use the Force to manipulate objects around him. It was this aspect of the Force that was perhaps the least understood of the three, a fact that was all the more obvious after the Jedi Purge. As Luke Skywalker set out to rebuild the Jedi Knights after the Battle of Endor, his own training led him to concentrate on the Living Force and Physical Force. It wasn't until the Yuuzhan Vong invaded the galaxy, and the Fosh Jedi Vergere returned from her self-imposed exile among them, that Luke began to consider what the Unifying Force meant to the new Jedi Knights.
