In the post titled: Evidence for rebirth
In point number 3 it says:
“3. However, when one attains the Arahant stage, certain “extrasensory powers” are gained; the ability to “see” previous lives (pubbe nivasanussati nana) is one of them.”
Now this is not necessarily correct because a pannavimutti arahant may not have any extra abilities and may not bother to develop them.
