Seven heavens

In religious or mythological cosmology, the seven heavens refer to seven levels or divisions of the Heavens. The concept, also found in the ancient Mesopotamian religions, can be found in Judaism and Islam; the Christian Bible does not mention seven levels of heaven, it mentions three; a similar concept is also found in some other religions such as Hinduism. Some of these traditions, including Jainism, also have a concept of seven earths or seven underworlds both with the metaphysical realms of deities and with observed celestial bodies such as the classical planets and fixed stars.
