Can you explain the purpose of the Gom Jabbar?
Sure. The Gom Jabbar is a fictional device in "Dune" used by the Bene Gesserit sisterhood to test the humanity and strength of potential members through subjecting them to intense pain. The test identifies those who are mentally strong enough to withstand intense physical pain, control their emotions, and overcome their instinct for self-preservation. It is a symbol of the Bene Gesserit's power and influence, and a reminder of the potential consequences of underestimating the strength and intelligence of women in a male-dominated society.
