Exalted concentration (Buddhism)

Here there is unification in profitable or moral consciousness of the fine-material and immaterial spheres (form-realm and formless realms).

According to Hinayana Buddhism, concentration is considered as of one kind (monad), of two kinds (dyads), of three kinds (triads), of four kinds (tetrads) or of five kinds (pentad). In the fourth triad, this is the second concentration.
