俱舍論頌疏論本 24.19

24.19

行無色者差別有四，唯除中般，無中有故。從欲界沒，直生無色，有生般等四種那含，此總名為無色那含，足前成六。或有不生色界、無色界，唯於欲界得般涅槃，名現般那含，於現身中得涅槃故。頌言「住此般涅槃」者，即住此欲界，名現般也。此兼前六成七不還。

Those who proceed to the formless have four distinctions, excluding only the intermediate-state parinirvāṇa, because there is no intermediate existence [in the formless realm]. Dying from the desire realm, they are reborn directly into the formless realm; there are four kinds of anāgāmin, such as attaining parinirvāṇa upon birth, and these are collectively called formless anāgāmins, which added to the previous ones make six. Or there are those who are not reborn in the form realm or the formless realm, but attain parinirvāṇa in the desire realm alone; these are called 'anāgāmins who attain parinirvāṇa in the present [existence]', because they attain nirvāṇa in the present body. When the verse says 'remaining here, one attains parinirvāṇa', 'here' means remaining in this desire realm, called attaining parinirvāṇa in the present. This, combined with the previous six, constitutes the seven non-returners.
