17.29

無色無想天，前七唯成就者，謂聖人生無色界，成就過、未無漏七支律儀，彼無色故，必不現行。無想天中，以無心故，亦不現行，唯成就過、未靜慮律儀。然無色那含於過去欲色界五地身中，隨依何地，或二三四五地，曾起曾滅無漏律儀，生無色時，成彼過去曾起一地，成過去一地戒，乃至曾起五地，成過去五地戒也。若未來世，依五地身無漏律儀皆定成就（五地：欲界、四靜慮也）。

'In the formless and the heaven of non-conception, / The first seven are only possessed' means that when a noble one is born in the formless realm, they possess the past and future untainted seven factors of restraint; because that [realm] is formless, they definitely do not manifest. In the heaven of non-conception, because of being without mind, they also do not manifest; they only possess the past and future restraint of meditative concentration. However, when a formless non-returner (anāgāmin), in past bodily existences of the five stages of the desire and form realms, depending on whichever stage—whether two, three, four, or five stages—had previously aroused and previously ceased untainted restraint, is born into the formless realm, they possess the past precepts of one stage previously aroused, up to possessing the past precepts of five stages previously aroused. As for the future, the untainted restraints based on the bodily existences of the five stages are all definitely possessed (the five stages: the desire realm and the four dhyānas).
