AxelSnaxel is correct. Those pannavimutti arahants have not cultivated jhana, and thus are not able to recall previous lives.
– So, I simply deleted that sentence in the post.
However, people who cultivate even anariya jhana to higher jhanic states can recall past lives. Some of these abilities just come from previous lives (for those who had cultivated such higher jhanas in previous lives), which may be what y not is referring to.
Thanks for pointing it out, AxelSnaxel. The goal is to have full inter-consistency within the website and also with the Tipitaka.
Yes. This is a good topic where people can report inconsistencies they find.
