In philosophy and religion, the word noetic, from the Greek νοῦς (nous) is usually translated as "mind", "understanding", "intellect", or "reason". Most dictionaries define the term noetic as a synonym of "mental" or "intellectual." From the nous emerges the world soul, which gives rise to the manifest realm.
