easons. (a) The sutta lists the categories in ascending order, and thereâs little reason to class one who takes 400 eons to attain unbinding higher than one who takes only 100 eons to do so. (b) The second category actually includes the first, so there would seem to be little reason to distinguish them as two separate categories. It would make better sense to define the categories this way: One who attains unbinding relatively soon after arriving in a Pure Abode is one unbound on arrival. One who attains unbinding after leaving the human realm but before reaching a Pure Abode would be one unbound in between. See also: MN 70; SN 12:68; SN 22:89; AN 4:131; AN 9:36; AN 10:13 - --> - - - -
