These various planes of existence can be found in countless world systems (loka-dhatu), which are born, expand, contract and are destroyed in a cyclical nature across vast expanses of time (measures in kappas). This cosmology is similar to other ancient Indian systems, such as the Jain cosmology. This entire cyclical multiverse of constant birth and death is called samsara. Outside of this system of samsara is nibbana (lit. "vanishing, quenching, blowing out"), a deathless (amata) and transcendent reality, which is a total and final release (vimutti) from all suffering (dukkha) and rebirth.Buswell Jr., Robert E.; Lopez Jr., Donald S.
