Various suttas mention various 'planes' or 'levels' or 'realms' of existence; for example:
Scattered throughout the suttas are references to as many as thirty-one distinct "planes" or "realms" of existence into which beings can be reborn during their long wandering through samsara. These range from the extraordinarily grim and painful hell realms all the way up to the most exquisitely refined and blissful heaven realms. Existence in every realm is temporary; in Buddhist cosmology there is no eternal heaven or hell. [etc.]
The realms of existence are customarily divided into three distinct "worlds" (loka), listed here in descending order of refinement:
The Immaterial World (arupa-loka). Consists of four realms that are accessible to those who pass away while meditating in the formless jhanas.
The Fine-Material World (rupa-loka). Consists of sixteen realms [etc.]
The Sensuous World (kama-loka). Consists of eleven realms [etc.]
The information on this page was assembled from a variety of sources. In the interests of economizing space I have not attributed each fact to its respective source.
I don't want to ask for a precise list, but how or what should I understanding these realms are?
I have heard several versions now of what "levels of existence" are:
- Some say it is like physical, or is it mental (psychological), biomes in this universe?
- Others say it is other universes or even other dimensions?
