Emptiness, a Force ability rooted in Control, enabled practitioners to achieve a profound meditation by clearing their thoughts and surrendering to the currents of the Force. During this state, they became unaware of the external world, experiencing typical physical needs like thirst and hunger. Those immersed in Emptiness proved elusive to Force detection, and Force-based attacks directed towards them were largely ineffective. Upon emerging from Emptiness, the connection to the Force was refreshed and enhanced, granting the user increased command over it for a short duration.
