Bailey described a concept of racial differentiation that posited a division of humanity into races that are on different levels in a "ladder of evolution". These '"races" do not represent a national or physical type but a stage of evolution. For example, she states that the Aryan root race (or '5th race'), is an "emerging new race" and so a relative new evolutionary phenomena. She stated that this newer type is forming in every land but primarily in lands where Caucasian peoples are found and indicates a culture where thought or intellect is dominant. She stated that as evolution proceeds, things are accelerated and humanity will soon be predominantly distinguished by the Aryan consciousness. "I speak not in terms of the Aryan race as it is generally understood today or in its Nordic implications."
