Understanding having a measureless object (Buddhism)

This is understanding that occurs contingent on nirvana or nibbana. This is transcendental or supramundane insight.

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 second triad, this is compared with understanding having a limited or exalted object.
