Core to the tenets of Lazarism is the belief that one could defeat the cycle of life and death by killing the body but preserving the spirit. By being in an intermediate state, death is defeated. However, in a seemingly contradictory statement, death is necessary to defeat life.

The Lazarus pool acts as a safeguard for the spirit to remain within the material world while the body is destroyed and remade. The process takes an entire day to complete and only lasts for a week before the body has to be rebuilt.
