20.37

As for 'For the form realm, three each of its own and the lower, one of the higher, and pure consciousness are the domains': what are bound to the form realm and abandoned by suffering, origin, and cultivation are each taken as an object by eight consciousnesses; namely, three of their own realm and three of the lower realm—'lower' meaning the desire realm, and 'three' meaning what are abandoned by suffering, origin, and cultivation as stated above—together with one of the higher realm, meaning the consciousness abandoned by cultivation in the formless realm because it can take the suffering, origin, and cultivation of the form realm as an object, in addition to the uncontaminated pure consciousness also taking what are abandoned by suffering, origin, and cultivation in the form realm as an object. Each of these eight consciousnesses can take what are abandoned by suffering, origin, and cultivation in the form realm as an object.
