The Fine-Material World
(rupa-loka).
Consists of sixteen realms whose inhabitants (the devas) 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 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.
You are here for now. Rebirth as a human being is extraordinarily rare (SN 56.48). It is also extraordinarily precious, as its unique balance of pleasure and pain (SN 35.135) facilitates the development of virtue and wisdom to the degree necessary to set one free from the entire cycle of rebirths.
