Formless realm
Formless realm (Skt. arūpadhātu; Wyl. gzugs med khams) — the third of the three realms, where gods without any form dwell in four types of perception spheres.
Four Perception Spheres (Tib. སྐྱེ་མཆེད་མུ་བཞི་, Wyl. skye mched mu bzhi)
- Infinite Space (Skt. ākāśānantyāyatana; Tib. ནམ་མཁའ་མཐའ་ཡས་, nam mkha’ mtha’ yas)
- Infinite Consciousness (Skt. vijñānanyāyatana; Tib. རྣམ་ཤེས་མཐའ་ཡས་, rnam shes mtha’ yas)
- Nothing Whatsoever (Skt. ākiṃcanyāyatana; Tib. ཅི་ཡང་མེད་པ་, ci yang med pa)
- Neither Existence Nor Non-existence (Skt. naivasaṃjñānasaṃjñāyatana; Tib. ཡོད་མིན་མེད་མིན་, yod min med min). Being the highest possible state in worldly existence, this fourth sphere is also called the Peak of Existence (Tib. སྲིད་པའི་རྩེ་མོ་, Wyl. srid pa'i rtse mo).
