The Fourth Earth
Unitists belong to a specific religion as named and is very similar to Dualism.
Unitists do not believe in deities at all, and some believe only loosely in a God if at all. The core belief is that the Universe (referred to as the Unity) is one integral organism, and that all life and matter are simply parts of the Unity.
The Unity is sometimes referred to as having a concious will, and sometimes not.
Unitists do not believe in an afterlife in the way many other religions do, but rather believe that a person’s life force simply merges with the Unity, adding the individual’s consciousness, memories and experience to the greater collective. The common analogy is that a person’s life is but a drop of ocean spray in the air before it finally returns to the ocean.
Given that souls come from the greater Unity, of which the memories and lives of those dead have rejoined, many Unitists claim to have memories from past lives, and varying degrees of reincarnation are common.
