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 (skye mched mu bzhi)
- Infinite Space (nam mkha’ mtha’ yas)
- Infinite Consciousness (rnam shes mtha’ yas)
- Nothing Whatsoever (ci yang med pa)
- Neither Existence Nor Non-existence (yod min med min). Being the highest possible state in worldly existence, this fourth sphere is also called the Peak of Existence (Wyl. srid pa'i rtse mo).
