The term deva (देव Sanskrit) refers to all ethereal beings that reside in the heavens and are reborn there as the result of good karma. From a human perspective, devas manifest divine qualities and are invisible to the physical human eye. Through extrasensory perception that can be attained through practice, some humans can open the divyacakṣus that can enable them to see beings from other planes. Some human beings can also develop auditory powers to be hear the voices from the ethereal world.
