Mind

Mind was the third school, or focus, taught by the Sith to use the Force. The Sith channeled the dark side of the Force for the disciplines of Mind, which drew from the unifying Force and operated in the realm of thought and memory rather than the physical plane; thus, they required psychic strength rather than physical. Crucitorn, Hatred, Horror, Memory Walk, and Mind Shard were associated with Mind.
