In religious or mythological cosmology, the seven heavens refer to the seven divisions of the Heaven, the abode of immortal beings, or the visible sky, the expanse containing the Sun, Moon and the stars. This concept dates back to ancient Mesopotamian religions and similar concept is also found in some Indian religions such as Hinduism, and in some Abrahamic religions such as Judaism, Islam and Catholicism. Some of these traditions also have concept of seven earths or seven underworlds, which also includes Jainism.
