[804] Where the masculinity faculty (purisindriya) has never arisen, has the equanimity faculty (upekkhindriya) never arisen there?
In the form sphere (rūpāvacara) and in the formless sphere (arūpāvacara), the masculinity faculty has never arisen there, but it is not the case that the equanimity faculty has never arisen there. Among the non-percipient beings (asaññasatta), both the masculinity faculty has never arisen there and the equanimity faculty has never arisen.
Or else, where the equanimity faculty has never arisen, has the masculinity faculty never arisen there?
Yes.
