1. Are these realms inhabited by anagamins and arahants alone? (AbdS. noted above suggests so.) A passing note in the Simhanada-Sutta (MN 20.57) has the Buddha saying, "...had I passed through the round as a god in the Pure Abodes, I would never have returned to this world". So in any case, it's a one-way-only realm, it seems, to where beings are "spontaneously born" only to be liberated.
2. While it's said that this abode is inhabited by anagamins and arahants, presumably the "arahants" means those anagamins who became arahants there, since an arahant wouldn't take another birth anywhere.
3. Can someone point to textual references in the Suttas or the Abhidhamma where the topic is reviewed in more detail? A few notes of interest as follows: The Jhana-sutta (of AN 4.123) mentions a noble disciple in the 4th jhana attaining the Vehapphala ("great-fruit") realm; and from there attains arahantship. Second Jhana-sutta (AN 4.124) appears to say that any form-jhana may lead to a pure abode? The Sekhin Sutta (AN 3.86) speaks simply of eliminating the five lower fetters ie. being an anagamin. Again, the Metta Sutta (AN 4.126) grants Suddhavasa access for pervading all directions with Metta (which is said to only reach the 3rd jhana) and/or other Brahmaviharas.
4. And what about the Tusita-realm, said to be the dwelling of e.g. Bodhisatta Metteyya? Curiously it is within the upper bounds of the Kama-loka or the sense-realm. Why would that be the last dwelling of the Buddhas-to-be, what qualities and conditions does it have to be so distinguished?
5. And finally, on something of a side-track. It is said that Brahma Sahampati (who famously inspired the Buddha to spread the sasana) also dwells within the Suddhavasa. Is it that all the realms from the 1st-jhana sphere upwards are called Brahma-worlds; and all beings there are Brahmas of sorts?
Insights most welcome from the good assembly here. May all beings not return. Save for the Bodhisattas!
