Buddhists teach ten spiritual realms:
Hell (suicidal); Hunger (insatiable desires or addiction); Animality (amorality); Anger (considering ourself more virtuous and more important than others); Humanity; Rapture; Learning; Realization; Bodhisattva (or Saintliness); and a condition of pure, indestructible happiness which is not dependent on one’s circumstances.
I’ve been in them all – I believe you have too.
We are, and have, worlds within worlds.
