Formless Realm; 無色界; Tibetan: གཟུགས་མེས་ཁམས (zuk may kham); Wylie: gzugs mes khams; Sanskrit: Arupadhatu, Arupalok;
Formless Realm is the third of Three Realms. Beings born here have only a subtle form and are mostly absorbed in deep meditative states where the processes of thoughts and perception have ceased. They have no bodies and no environments. Formless Realm has four heavens:
- Akasanantyayatana, Heaven of boundless space;
- Vijnananantyayatana, Heaven of boundless knowledge;
- Akincanyayatana, Heaven of nothing, or nonexistence
- Naivasanjnanasanjnayatana, the state of neither thinking nor not thinking
無色界是三界之三。無色界眾生前生死時進入禪定狀態，想與識過程皆息滅，故無色身亦無所依境。四無色界包括:
- 空無邊處
- 識無邊處
- 無所有處
- 非想非非想處
