Understanding accompanied by equanimity (Buddhism)

Here understanding is that belonging to two of the classes of profitable or moral consciousness associated with the sense sphere, and belonging to the four kinds of path consciousnesses associated with the fifth jhana of the fivefold method.

On the Path of Purification of Hinayana Buddhism, panna (understanding) is considered as of one kind (monad), of two kinds (dyads), of three kinds (triads) or of four kinds (tetrads). There are five dyads, four triads and two tetrads. All have the characteristic of penetrating the individual essences or true nature of states (monad). In the fourth dyad, this is contrasted with understanding accompanied by joy.
