 | | There are eight stages of meditative absorption; the first four are the absorptions of form (rupajhana), and the remaining ones are formless absorptions (arupajhana), the highest of which is known as the Sphere of Neither-Perception-Nor-Non-Perception (nevasañña-nasañña-yatana). |
 | | However, if one consistently perseveres until attainment concentration (appana samadhi) is gained, one may continue to achieve any of the eight levels of absorption. |
 | | The other four are called absorptions of the formless sphere (arupajhana) because, rather than focusing the mind on any concrete form, the meditator employs abstract concepts as objects of concentration. |
