A female Jedi using Empty Meditation
Empty Meditation, alternatively referred to as the Meditation of Emptiness, served as a method employed by the Jedi Order to eliminate emotions and establish an emotional foundation.
This meditative skill was imparted to Jedi Knights, and it required them to clear their minds of all feelings and embrace the Force. By releasing their emotions and sentiments, practitioners were able to ground themselves in pure power and the strength of the Force. Jedi Masters likened this process to discovering a serene point within the chaos of one's emotions.
Through this practice, every memory, thought, and feeling was either disregarded or perceived as mere shadows, enabling a Jedi to attain a state of complete tranquility.
The Meditation of Emptiness also proved to be a useful tactic for a Jedi to defend against external mental manipulation or assaults, such as the Jedi mind trick.
