俱舍論疏 19.64

19.64

論「又由有人至非真解脫」，第二釋也。前以上界緣內有，故名為有貪。後以止邪執故，於上二界立有貪名。

On the passage where the Śāstra says, 'Furthermore, because there are persons who [...] it is not genuine liberation': This is the second explanation. Previously, because the upper realms objectify internal existence, it is called existence-attachment. Later, in order to halt erroneous graspings, the name existence-attachment is established for the upper two realms.
