کیهانشناسی دینی (همچنین کیهان شناسی اساطیری) روشِ توضیحِ منشا، تاریخچه و تکامل جهان هستی بر اساسِ اسطوره شناسی دینیِ یک سنت خاص است.
جهانِ اسرائیل باستان از یک زمین دیسک مانند و تختِ شناور در آب ساخته شده بود که آسمان و بهشت در بالا و دنیای مردگان در زیرِ آن قرار داشتند. در دورهٔ هلنی (پس از BCE c.330) یهودیان شروع به قبول ایدهٔ یونانیان کردند که میتواند مکانی برای مجازاتِ کردارِ بد و نیز لذتِ زندگی پس از مرگ در آسمانها وجود داشته باشد.
در اسطورههای ایرانی جهان هستی به چهار دوره سه هزار ساله تقسیم میشود. در سه هزار سال اول که دوره اصلی است، همه چیز در حال سکون و آرامش و جهان غیر مرئی است. این جهان به دو بخش تقسیم میشود. یک دنیای زیبا و اهورایی و یک دنیای اهریمنی و تاریک. اهورامزدا از وجود اهریمن آگاه است، اما اهریمن که در قعر تاریکی است، از وجود اهورامزدا بیاطلاع است. در سه هزار سال میانه که با خواب اهریمن آغاز میشود، اهورامزدا با استفاده از این فرصت دست به کار ساختن شش پیش نمونه جهان هستی یعنی آسمان، آب، زمین، گیاه، چهارپایان و بالاخره انسان میشود. در این دوره همچنین هفت اَمشاسپَند (هفت جلوه مینوی) زاده میشوند. این فرشتگان مقرب عبارتند از:
اسلام میآموزد که خدا جهان را و از جمله زمین و انسان را به وجود آوردهاست. والاترین هدف، تجسم جهان به عنوان کتابِ نمادها برای مراقبه و تفکر جهتِ تعالی معنوی است یا به عنوان یک زندان که از آن روح انسان برای رسیدن به آزادی واقعی در یک سفر روحانی به سوی خدا میگریزد.
Religious cosmology is an explanation of the origin, evolution, and eventual fate of the universe, from a religious perspective. This may include beliefs on origin in the form of a creation myth, subsequent evolution, current organizational form and nature, and eventual fate or destiny. There are various traditions in religion or religious mythology asserting how and why everything is the way it is and the significance of it all. Religious cosmologies describe the spatial lay-out of the universe in terms of the world in which people typically dwell as well as other dimensions, such as the seven dimensions of religion; these are ritual, experience and emotional, narrative and mythical, doctrinal, ethical, social, and material. Religious mythologies may include descriptions of an act or process of creation by a creator deity or a larger pantheon of deities, explanations of the transformation of chaos into order, or the assertion that existence is a matter of endless cyclical transformations. Religious cosmology differs from a strictly scientific cosmology informed by the results of the study of astronomy and similar fields, and may differ in conceptualizations of the world's physical structure and place in the universe, its creation, and forecasts or predictions on its future. The scope of religious cosmology is more inclusive than a strictly scientific cosmology (physical cosmology) in that religious cosmology is not limited to experiential observation, testing of hypotheses, and proposals of theories; for example, religious cosmology may explain why everything is the way it is or seems to be the way it is and prescribing what humans should do in context. Variations in religious cosmology include those of Indian origin, such as Buddhism, Hindu, and Jain; the religious beliefs of China; and, the beliefs of the Abrahamic faiths, such as Judaism, Christianity, and Islam. Religious cosmologies have often developed into the formal logics of metaphysical systems, such as Platonism, Neoplatonism, Gnosticism, Daoism, Kabbalah, or the great chain of being.
Judaism and Christianity
The universe of the ancient Israelites was made up of a flat disc-shaped earth floating on water, heaven above, underworld below. Humans inhabited earth during life and the underworld after death, and the underworld was morally neutral; only in Hellenistic times (after c.330 BC) did Jews begin to adopt the Greek idea that it would be a place of punishment for misdeeds, and that the righteous would enjoy an afterlife in heaven. In this period too the older three-level cosmology was widely replaced by the Greek concept of a spherical earth suspended in space at the centre of a number of concentric heavens.
The belief that God created matter is called creatio ex nihilo. It is the accepted orthodoxy of most denominations of Judaism and Christianity. Most denominations of Christianity and Judaism believe that a single, uncreated God was responsible for the creation of the cosmos.
Islam teaches that God created the universe, including Earth's physical environment and human beings. The highest goal is to visualize the cosmos as a book of symbols for meditation and contemplation for spiritual upliftment or as a prison from which the human soul must escape to attain true freedom in the spiritual journey to God.
Below here there are some other citations from the Quran on cosmology.
"And the heavens We constructed with strength, and indeed, We are [its] expander." 51:47 Sahih International
"Do not the unbelievers see that the heavens and the earth were joined together (as one unit of creation), before We clove them asunder? We made from water every living thing. Will they not then believe?" 21:30 Yusuf Ali translation
"The day that We roll up the heavens like a scroll rolled up for books (completed),- even as We produced the first creation, so shall We produce a new one: a promise We have undertaken: truly shall We fulfil it." 21:104 Yusuf Ali translation
In Buddhism, like other Indian religions, there is no ultimate beginning nor final end to the universe. It considers all existence as eternal, and believes there is no creator god. Buddhism views the universe as impermanent and always in flux. This cosmology is the foundation of its Samsara theory, that evolved over time the mechanistic details on how the wheel of mundane existence works over the endless cycles of rebirth and redeath. In early Buddhist traditions, Saṃsāra cosmology consisted of five realms through which wheel of existence recycled. This included hells (niraya), hungry ghosts (pretas), animals (tiryak), humans (manushya), and gods (devas, heavenly). In latter traditions, this list grew to a list of six realms of rebirth, adding demi-gods (asuras). The "hungry ghost, heavenly, hellish realms" respectively formulate the ritual, literary and moral spheres of many contemporary Buddhist traditions.
According to Akira Sadakata, the Buddhist cosmology is far more complex and uses extraordinarily larger numbers than those found in Vedic and post-Vedic Hindu traditions. It also shares many ideas and concepts, such as those about Mount Meru. The Buddhist thought holds that the six cosmological realms are interconnected, and everyone cycles life after life, through these realms, because of a combination of ignorance, desires and purposeful karma, or ethical and unethical actions.
The Hindu cosmology, like the Buddhist and Jain cosmology, considers all existence as cyclic. With its ancient roots, Hindu texts propose and discuss numerous cosmological theories. Hindu culture accepts this diversity in cosmological ideas and has lacked a single mandatory view point even in its oldest known Vedic scripture, the Rigveda. Alternate theories include a universe cyclically created and destroyed by god, or goddess, or no creator at all, or a golden egg or womb (Hiranyagarbha), or self-created multitude of universes with enormous lengths and time scales. The Vedic literature includes a number of cosmology speculations, one of which questions the origin of the cosmos and is called the Nasadiya sukta:
Beyond its creation, Hindu cosmology posits divergent theories on the structure of the universe, from being 3 lokas to 12 lokas (worlds) which play a part in its theories about rebirth, samsara and karma.
The complex cosmological speculations found in Hinduism and other Indian religions, states Bolton, is not unique and are also found in Greek, Roman, Irish and Babylonian mythologies, where each age becomes more sinful and of suffering.
Jain cosmology considers the loka, or universe, as an uncreated entity, existing since infinity, having no beginning or an end. Jain texts describe the shape of the universe as similar to a man standing with legs apart and arm resting on his waist. This Universe, according to Jainism, is narrow at the top, broad at the middle and once again becomes broad at the bottom.
There is a "primordial universe" Wuji (philosophy), and Hongjun Laozu, water or qi. It transformed into Taiji and multiplied into everything. The Pangu legend tells a formless chaos coalesced into a cosmic egg. Pangu emerged (or woke up) and separated Yin from Yang with a swing of his giant axe, creating the Earth (murky Yin) and the Sky (clear Yang). To keep them separated, Pangu stood between them and pushed up the Sky. After Pangu died, he became everything.
Esoteric cosmology is cosmology that is an intrinsic part of an esoteric or occult system of thought. Esoteric cosmology maps out the universe with planes of existence and consciousness according to a specific worldview usually from a doctrine.
Gnostic teachings were contemporary with those of Neoplatonism. Gnosticism is an imprecise label, covering monistic as well as dualistic conceptions. Usually the higher worlds of Light, called the Pleroma or "fullness", are radically distinct from the lower world of Matter. The emanation of the Pleroma and its godheads (called Aeons) is described in detail in the various Gnostic tracts, as is the pre-creation crisis (a cosmic equivalent to the "fall" in Christian thought) from which the material world comes about, and the way that the divine spark can attain salvation.
Serer religion posits that, Roog, the creator deity, is the point of departure and conclusion. As farming people, trees play an important role in Serer religious cosmology and creation mythology. The Serer high priests and priestesses (the Saltigues) chart the Star of Sirius known as Yoonir in the Serer language and some of the Cangin languages. This star enables them to give accurate information as to when Serer farmers should start planting seeds among other things relevant to Serer lives and Serer country. The Star of Yoonir is the symbol of the universe in Serer cosmology and creation mythology.
