The Force Unchained
" …Sense involves the next step, in which the Jedi recognizes the Force in the universe outside herself. "
Classified as Sense abilities by the Jedi Order, these techniques were taught to Padawans to broaden the scope of their Control abilities. Dipping into a deeper understanding of the Living Force, Sense abilities allowed Force-wielders to immerse themselves in the environment. By the end of their apprenticeship, Padawans were expected to use the Force as an additional sense, constantly attuned to the undulation of the Force.
The Jedi Order saw the Sense abilities divided into four main groups: prima vitae, tactus otium, tai vordrax/psychometry, and projected telepathy. While there were many other styles to the Sense family, these were considered the most vital to Jedi teachings.
