[887] Where the masculinity faculty (purisindriya) will arise, will the equanimity faculty (upekkhindriya) arise there?
Yes.
Or rather, where the equanimity faculty will arise, will the masculinity faculty arise there?
In the form sphere (rūpāvacara) and the formless sphere (arūpāvacara), the equanimity faculty will arise there, but the masculinity faculty will not arise there. In the sense sphere (kāmāvacara), there both the equanimity faculty will arise and the masculinity faculty will arise.
