Understanding consisting in development (Buddhism)

This is understanding that has reached absorption, having been acquired through an attainment of ecstasy in meditative development.

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 first triad, this is compared with understanding consisting in what is reasoned or what is learned.
