The importance of transformations marks the Dune universe, from the Bene Gesserit’s spice agony ritual that transforms acolytes (Bene Gesserit Sisterhood trainees) into Reverend Mothers to the extreme metamorphosis of Leto II into a giant sandworm to save humankind. One of the central themes in Heretics of Dune is the need for the Bene Gesserit to change and alter their ingrained principles to survive and thrive. Such changes permit the widening of perspectives, the expansion of knowledge, and the challenge to the status quo that perpetuates inequalities and stifles individual autonomy. 

The Bene Gesserit relies on spice precisely for its transformative properties, yet the ritual’s results are far from a radical change. The spice agony allows their acolytes to unlock millennia of Other Memories and exponentially expand their access to knowledge throughout the ages. However, such expansion remains limited to the Bene Gesserit’s controlled lineage of Reverend Mothers. Lucilla regards her Other Memories as capable of providing her with clues, but she acknowledges “their linear selectivity and confinement to the female side” (10). The ritual may broaden their perspective, but the points of view are all essentially from other Bene Gesserit who are often like-minded.
