[883] Where the femininity faculty (itthindriya) will arise, will the equanimity faculty (upekkhindriya) arise there?
Yes.
Or rather, where the equanimity faculty will arise, will the femininity faculty arise there?
In the form sphere (rūpāvacara) and the formless sphere (arūpāvacara), the equanimity faculty will arise there, but the femininity faculty will not arise there; in the sensual sphere (kāmāvacara), there both the equanimity faculty will arise and the femininity faculty will arise.
