(Skt.; Pāli). Attainment or equipoise; a state where the body and mind abide in a state of tranquil composure. Often, samāpatti refers to the four trances (dhyānas), the four levels of the Formless Realm (ārūpya-dhātu), and the state of cessation (nirodha-samāpatti). It is also used as an equivalent to samādhi.
