10.45

Regarding "the two [dhyānas] have twelve cognizing the desire [realm]": "the two" means the first dhyāna and the second dhyāna. These first and second dhyānas are bound to only twelve: namely, six of joy and six of equanimity, only excluding the six of grief, because that realm lacks grief. In cognizing objects of the desire realm, there are also twelve in total, excluding the six grief objects.
