Concentration with happiness (Buddhism)

The mind is unified in two jhanas (in the fourfold reckoning) or five jhanas (in the fivefold reckoning). This is one way of experiencing access concentration.

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 third dyad, this contrasts with concentration without happiness.
