Ancient writings from various cultures and traditions, including the Bible and derivative works, often describe multiple levels of heaven, each representing different realms of existence, spiritual attainment, or cosmic order. These layered heavens, sometimes numbered as three, seven, or more, are depicted as ascending planes, with lower levels being closer to the earthly realm and higher levels representing divine or ultimate enlightenment. Such beliefs reflect diverse understandings of the universe, the afterlife, and the relationship between humanity and the divine, offering symbolic insights into spiritual progress and cosmic hierarchy.
