Trailokya


Trailokya literally means "three worlds". It can also refer to "three spheres," "three planes of existence," and "three realms".
Various schemas of three realms appear in the main Indian religions of Hinduism, Buddhism and Jainism.

The concept of three worlds has a number of different interpretations in Hindu cosmology.

  • Rūpa-loka, a realm predominantly free of baser desires, populated by higher level devas. It is a possible rebirth destination for those well practiced in dhyāna.
  • Arūpa-loka, a non-corporeal realm populated with four heavens. It is a possible rebirth destination for practitioners of the four formlessness stages of meditation.
