To Hindus, Devaloka is a plane of blissful existence that can be reached as soon as one is sufficiently attuned to light and good. However, to become even better and to learn more, one must return to a life on Earth, until all the learning possibilities here have been exhausted. Then, any other lives become unnecessary and liberation (moksha) is achieved. When that happens, the practitioner can even reach higher planes, such as Vaikuntha and Sivaloka (Kailasa), places of union with Vishnu and Shiva.
In Buddhism, a deva loka is a dwelling place of the Buddhist devas. The worlds of the devas differ greatly from each other depending on the nature of their inhabitants. See Buddhist cosmology.
