Buddhism in a Nutshell
The 31 Planes of Existence

The realms of existence are customarily divided into three distinct "worlds" (loka), listed here in descending order of refinement:

  1. The Immaterial World (arupa-loka).

    Consists of four realms that are accessible to those who pass away while meditating in the formless jhanas.

  2. The Fine-Material World (rupa-loka).

    Consists of sixteen realms whose inhabitants (the brahmas) experience extremely refined degrees of mental pleasure. These realms are accessible to those who have attained at least some level of jhana and who have thereby managed to (temporarily) suppress hatred and ill-will. They are said to possess extremely refined bodies of pure light. The highest of these realms, the Pure Abodes, are accessible only to those who have attained to "non-returning", the third stage of Awakening. The Fine-Material World and the Immaterial World together constitute the "heavens" (sagga).

  3. The Sensuous World (kama-loka).

    Consists of eleven realms in which experience -- both pleasurable and not -- is dominated by the five senses. Seven of these realms are favorable destinations, and include our own human realm as well as several realms occupied by devas. The lowest realms are the four "bad" destinations, which include the animal and hell realms.

Arupa-Loka
(Non-Material World)

Formless Beings

Fourth Jhana Plane
Third Jhana Planee
Second Jhana Plane
First Jhana Plane
There are only 4 planes of existence here



Rupa-Loka
(Fine-Material World)

Fine-Body Beings

Fourth Jhana Realm
Third Jhana Realm
Second Jhana Realm
First Jhana Realm
The first 3 jhanic realms has 3 planes of existence each, and the fourth jhanic plane has 7 planes, thus 3+3+3+7 = 16 planes of existence

Kama-Loka
(Sensuous World)

Devas, Humans and 4 Woeful states


Deva Realm
Human Realm
Animal Realm
Asura Realm
Peta Realm
Hell Realm
The Deva Realm has 6 planes (Planes of the 4 Great Kings, Plane of the 33 Gods, Yama Devas Plane, Contented Devas Plane, Devas delighting in Creation, Devas having power over creation of others), then the Human Realm, and then followed by the 4 Woeful Planes of existence, thus 6 + 1 + 4 = 11 planes of existence
