I want to know the answer to the following question:
Rebirth into the Śuddhāvāsa Worlds or Pure Abodes can only be attained by who?
All the background I'm provided with is that "The above are further subdivided into 31 planes of existence.[web 4] Rebirths in some of the higher heavens, known as the Śuddhāvāsa Worlds or Pure Abodes, can be attained only by skilled Buddhist practitioners known as anāgāmis (non-returners).". Is that enough to answer the question?
Answer: yes
