The Bene Gesserit martial arts techniques, so named by outsiders who witnessed their seemingly supernatural fighting abilities. Based on supreme prana-bindu control, the weirding way encompassed hand-to-hand combat, knife fighting, and whip techniques of extraordinary ferocity. Practitioners could move with speed and precision that appeared superhuman to the untrained eye. Paul Atreides taught adapted versions of these techniques to the Fremen, dramatically enhancing their already formidable combat abilities and contributing to their military victories against the Sardaukar and Harkonnen forces.
