Beyond the Heavenly Shell
Ancient explanations of celestial bodies through the theory of “hun-tian” suggest that heaven and earth are one entity, like an egg. When the yolk and white of the egg are undivided, the world remains in a state of chaos. Once the yolk separates from the white, heaven and earth are formed. Humans cannot exist outside this eggshell. Therefore, the Taoist belief in the existence of thirty-three heavens beyond seems somewhat far-fetched.
