Reverend Mother

A Reverend Mother is a Bene Gesserit woman who has undergone the full priestess training. The final step to achieve the status of Reverend Mother involves ingesting a poison and changing that poison to a harmless substance within the body. The process allows the woman to now look into her past and access the thoughts and memories of other Reverend Mothers.

The leader of the Bene Gesserit through the first few books is Gaius Helen Mohiam. Jessica is also known as a Reverend Mother on Dune, once she goes through the ceremony. Her unborn daughter, Alia, is within her during the ceremony and also becomes a Reverend Mother at the same time.
