Most Goreans do not believe in immortality. The Initiate Caste though does believe in it and their Caste Codes are directed to that end. The regimen to achieve eternal life forms the foundation for many of their restrictions, such as avoiding meat and beans. The regimen also includes a study of mathematics. As women cannot belong to the Initiate Caste, then they cannot attain immortality. The Gorean land of the dead is called the "Cities of Dust."
