8.12

由生有四種者，此明無色雖無處所，由異熟生，差別有四：一、空無邊處天，修此定前，於加行位厭有色身，思無邊空，作空無邊解，名空無邊處。二、識無邊處，厭先外空，復思內識，作識無邊解，名識無邊處。三、無所有處，次厭無邊識，思無所有，作無所有解，名無所有處。四、非想非非想天，謂此定體非前七地麁想，名為非想。若想全無，便同癡暗，有細想故，名非非想。前三無色，從加行立名。第四無色，當體受稱。又論云：「復如何知彼無方處（問也）？謂於是處得彼定者，命終即於是處生故。復從彼沒，生欲、色時，即於是處中有起故。」解云（答前問也）：謂於是處得彼定者，謂隨何等洲，修得無色定處也。即於修定處，命終受無色界生，後時從無色沒生欲、色時，還即於過去修得定處中有起故，明知無色，無方所也。

"By rebirth there are four kinds": this explains that although the formless has no location, according to ripening-birth there are four differences: First, the Ākāśānantyāyatana heaven. Prior to cultivating this absorption, in the preparatory stage one tires of the material body, thinks upon boundless space, and forms the understanding of boundless space; it is named the Sphere of Boundless Space. Second, the Vijñānānantyāyatana: one tires of the previous external space, further contemplates internal consciousness, and forms the understanding of boundless consciousness; it is named the Sphere of Boundless Consciousness. Third, the Ākiñcanyāyatana: next, one tires of boundless consciousness, contemplates nothingness, and forms the understanding of nothingness; it is named the Sphere of Nothingness. Fourth, the Naivasaṃjñānāsaṃjñāyatana heaven: the essence of this absorption is not the coarse ideation of the previous seven planes, so it is named "neither ideation"; yet if ideation were entirely absent, it would be identical to dullness and ignorance, but subtle ideation exists, so it is named "nor non-ideation." The first three formless realms are named from their preparation. The fourth formless realm receives its designation from its own nature. Furthermore, the treatise states: "Again, how is it known that it has no spatial location? (A question.) Because where one attains that absorption, upon passing away one is reborn right in that place; and when passing away from there to be reborn in the desire or form realms, the intermediate existence arises right in that place." The explanation states (answering the preceding question): "where one attains that absorption" means whichever continent it was where one cultivated and attained the formless absorption. Reborn into the formless realm right where one cultivated the concentration upon passing away, later, when passing away from the formless to be reborn in the desire or form realms, the intermediate existence arises right in that place where one cultivated and attained the concentration in the past; hence one clearly knows that the formless has no spatial location.
