Seven levels or divisions of the Heavens in religious or mythological cosmology
In mythological or religious 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. 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.
Beliefs in the plurality of the heavens were not restricted to the belief in seven heavens. Ancient near eastern cosmology largely accepted the existence of three heavens. In Jewish cosmologies (albeit absent from the Hebrew Bible), the number of heavens could range from 3 to 365, with 7 being the most popular figure.
Origins.
The notion or belief in a cosmos structured or tiered into seven heavens likely originates or derives from the seven visible heavenly bodies (Mercury, Venus, Mars, Jupiter, Saturn, the Moon, and the Sun).
Greek astronomy and cosmology.
Each of the seven heavens corresponds to one of the seven classical planets known in antiquity. Ancient observers noticed that these heavenly objects (the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn) moved at different paces in the sky both from each other and from the fixed stars beyond them. Unlike comets, which appeared in the sky with no warning, they moved in regular patterns that could be predicted. They also observed that objects in the sky influenced objects on Earth as when movements of the sun affect the behavior of plants or movements of the Moon affect ocean tides.
Mesopotamian cosmology.
The concept of seven heavens as developed in ancient Mesopotamia where it took on a symbolic or magical meaning as opposed to a literal one. The concept of a seven-tiered was likely In the Sumerian language, the words for heavens (or sky) and Earth are An and Ki. The ancient Mesopotamians regarded the sky as a series of domes, usually three, but sometimes seven, covering the flat Earth. 
Each dome was made of a different kind of precious stone. The lowest dome of the heavens was made of jasper and was the home of the stars. The middle dome of heaven was made of "saggilmut" stone and was the abode of the Igigi. The highest and outermost dome of the heavens was made of "luludānītu" stone and was personified as An, the god of the sky. 
The celestial bodies were equated with specific deities. The planet Venus was believed to be Inanna, the goddess of love, sex, and war. The Sun was her brother Utu, the god of justice, and the Moon was their father Nanna. 
Ordinary mortals could not go to the heavens because it was the abode of the gods alone. Instead, after a person died, his or her soul went to Kur (later known as Irkalla), a dark shadowy underworld, located deep below the surface of the Earth. Sumerian incantations of the late second millennium BCE make references to seven heavens and seven earths. One such incantation is: "an-imin-bi ki-imin-bi" (the heavens are seven, the earths are seven.)
The understanding that the heavens can influence things on Earth lent heavenly, magical properties to the number seven itself, as in stories of seven demons, seven churches, seven spirits, or seven thrones. The number seven appears frequently in Babylonian magical rituals. The seven Jewish and the seven Islamic heavens may have had their origin in Babylonian astronomy.
In general, the heavens is not a place for humans in Mesopotamian religion. As Gilgamesh says to his friend Enkidu, in the Epic of Gilgamesh: "Who can go up to the heavens, my friend? Only the gods dwell with Shamash forever". Along with the idea of seven heavens, the idea of three heavens was also common in ancient Mesopotamia.
Abrahamic religions.
Judaism.
In the Talmud, it is suggested that the upper part of the universe is made up of seven heavens (Hebrew: "shamayim"):
The Jewish Merkavah and Hekhalot literature was devoted to discussing the details of these heavens, sometimes in connection with traditions relating to Enoch, such as the Third Book of Enoch.
Apocryphal texts.
The Second Book of Enoch, also written in the first century CE, describes the mystical ascent of the patriarch Enoch through a hierarchy of Ten Heavens. Enoch passes through the Garden of Eden in the Third Heaven on his way to meet the Lord face-to-face in the Tenth (chapter 22). Along the way, he encounters vividly described populations of angels who torment wrongdoers; he sees homes, olive oil, and flowers.
The book's depiction of ten heavens represented an expansion of the ancient seven-heaven model. This expanded cosmology was developed further in medieval Christianity.
Christianity.
The New Testament does not refer to the concept of seven heavens. However, an explicit reference to a third heaven appears in the Second Epistle to the Corinthians, penned in Macedonia around 55 CE. It describes the following mystical experience:
 ;templatestyles src="Template:Blockquote/styles.css" / ;I know a person in Christ who fourteen years ago was caught up to the third heaven—whether in the body or out of the body I do not know; God knows. And I know that such a person—whether in the body or out of the body I do not know; God knows—was caught up into Paradise and heard things that are not to be told, that no mortal is permitted to repeat.
The description is usually taken as an oblique reference by the author to himself. The passage appears to reflect first-century beliefs among Jews and Christians that the realm of Paradise existed in a different heaven than the highest one—an impression that may find support in the original Greek wording (closer to "caught away" than "caught up").
In the second century, Irenaeus also knows seven heavens (see his "Demonstration of Apostolic Preaching" 9; cf. "Against Heresies" 1.5.2).
Over the course of the Middle Ages, Christian thinkers expanded the ancient Mesopotamian seven-heaven model into a system of ten heavens. This cosmology, taught in the first European universities by the Scholastics, reached its supreme literary expression in The Divine Comedy by Dante Alighieri. The idea of seven heavens is carried over into the esoteric Christian cabala.
Islam.
The Quran and Hadith frequently mention the existence of seven "samāwāt" (سماوات), the plural of "samāʾ" (سماء), meaning 'heaven, sky, celestial sphere', and cognate with Hebrew "shamāyim" (שמים). Some of the verses in the Quran mentioning the "samaawat" are , and . The seven heavens are not final destinations for the dead after the Day of Judgment, but regions distinct from the earth, guarded by angels and inhabited by souls whose abode depends on their good deeds (fasting, jihad, Hajj, charity), with the highest layer, the closest to God. According to Quran and Hadiths, each of the skies has its own Qibla or a structure which became direction of prayer, similar to Kaaba of the mortal world, where the Qibla of highest heaven is called "Bayt al-Ma'mur", while the Qibla building for the lowest sky is called "Bayt al-Izza". 
In other sources, the concept is presented in metaphorical terms. Each of the seven heavens is depicted as being composed of a different material, and Islamic prophets are resident in each. The names are taken from Suyuti's Al-Hay’a as-samya fi l-hay’a as-sunmya:
There are two interpretations of using the number "seven". One viewpoint is that the number "seven" here simply means "many" and is not to be taken literally (the number is often used to imply that in the Arabic language). But many other commentators use the number literally.
One modern interpretation of "heavens" is that all the stars and galaxies (including the Milky Way) are all part of the "first heaven", and "beyond that six still bigger worlds are there," which have yet to be discovered by scientists.
Gnosticism.
The Gnostic text "On the Origin of the World" states that seven heavens were created in Chaos by Yaldabaoth below the higher realms, and each of them are ruled over by an Archon. During the end times, these heavens will collapse on each and the heaven of Yaldabaoth will split in two, causing its stars to fall upon the Earth, therefore causing it to sink into the Abyss.
In the Coptic Apocalypse of Paul, the apostle Paul ascends through the lower Seven Heavens. At the seventh heaven, he meets an old man who opens the gate to the realm beyond the material universe, and Paul then ascends to the eighth, ninth, and tenth heavens.
In Mandaeism, a series of "maṭartas", or "toll houses," are located between the World of Light ("alma ḏ-nhūra") from Tibil (Earth). The term "maṭarta" has variously been translated as "watch-station", "toll-station", "way-station", or "purgatory". Maṭartas are guarded by various uthras (celestial beings from the World of Light) and demons. In the Ginza Rabba, seven "maṭartas" are listed and described in of the "Right Ginza". 
However, the number of "maṭartas" is not always seven. of the "Right Ginza" (also known as the "Book of Dinanukht") lists six. of the "Left Ginza" lists eight. Alternatively, the Seven Heavens can also be seen as corresponding to the Seven Planets, who form part of the entourage of Ruha in the World of Darkness.
Hinduism.
According to all Puranas, the Brahmanda is divided into fourteen worlds known as "lokas". Seven are upper worlds: "Bhuloka" (the Earth and sky), "Bhuvarloka", "Svargaloka", "Maharloka", "Janarloka", "Tapaloka" and "Satyaloka"; and seven are lower worlds: "Atala", "Vitala", "Sutala", "Talatala", "Mahatala", "Rasatala" and "Patala".
