Within the Jedi Temple, Yoda is seen experiencing the deprivation ritual.
A deprivation ritual represented a specific type of meditation where a Jedi was placed inside a tank filled with liquid, with the air supply gradually being reduced. This process aimed to facilitate a deeper connection with the Force, pushing the Jedi as close to death as possible without actually succumbing to it. During the Clone Wars, after receiving communication from the spirit of Qui-Gon Jinn, Jedi Master Yoda underwent this deprivation ritual, being monitored by both Consular Jedi and doctor Rig Nema. While undergoing the ritual, he once again communicated with Jinn, and was instructed to journey to the planet known as Dagobah.
