Hindu cosmology is the description of the universe and its states of matter, cycles within time, physical structure, and effects on living entities according to Hindu texts. Hindu cosmology is also intertwined with the idea of a creator who allows the world to exist and take shape.[1]

Substance

All matter is based on three inert gunas (qualities or tendencies):[2][3][4]

There are three states of the gunas that make up all matter in the universe:[2][4][5][6][7][8]

  • pradhana (root matter): gunas in an unmixed and unmanifested state (equilibrium).
  • prakriti (primal matter): gunas in a mixed and unmanifested state (agitated).
  • mahat-tattva (matter or universal womb): gunas in a mixed and manifested state.

Pradhana, which has no consciousness or will to act on its own, is initially agitated by a primal desire to create from Purusha. The different schools of thought differ in understanding about the ultimate source of that desire and what the gunas are mixed with (eternal elements, time, jiva-atmas).[9][10]

The manifest material elements (matter) range from the most subtle to the most physical (gross). These material elements cover the individual, spiritual jiva-atmas (embodied souls), allowing them to interact with the material sense objects, such as their temporary material bodies, other conscious bodies, and unconscious objects.

Manifested subtle elements (a.k.a. antahkarana, the inner functions):[11][12][13][a]

Manifested physical (gross) elements (a.k.a. Pancha Bhuta, the five elements) and their associated senses and sense organs that manifest:[14][15][a]

  • akasha (aether) > sound > ear
  • vayu (air) > touch > skin
  • agni (fire) > sight/form > eye
  • apas (water) > taste > tongue
  • prithvi (earth) > smell > nose

Time

Time is infinite with a cyclic universe, where the current universe was preceded and will be followed by an infinite number of universes.[16][17] The different states of matter are guided by eternal kala (time), which repeats general events ranging from a moment to the lifespan of the universe, which is cyclically created and destroyed.[18]

The earliest mentions of cosmic cycles in Sanskrit literature are found in the Yuga Purana (c. 1st century BCE), the Mahabharata (c. 3rd century BCE – 4th century CE), and the Manusmriti (c. 2nd – 3rd centuries CE). In the Mahabharata, there are inconsistent names applied to the cycle of creation and destruction, a name theorized as still being formulated, where yuga (generally, an age of time)[19][20] and kalpa (a day of Brahma) are used, or a day of Brahma, the creator god, or simply referred to as the process of creation and destruction, with kalpa and day of Brahma becoming more prominent in later writings.[21]

Prakriti (primal matter) remains mixed for a maha-kalpa (life of Brahma) of 311.04 trillion years, and is followed by a maha-pralaya (great dissolution) of equal length. The universe (matter) remains manifested for a kalpa (day of Brahma) of 4.32 billion years, where the universe is created at the start and destroyed at the end, only to be recreated at the start of the next kalpa. A kalpa is followed by a pralaya (partial dissolution, a.k.a. night of Brahma) of equal length, when Brahma and the universe are in an unmanifested state. Each kalpa has 15 manvantara-sandhyas (junctures of great flooding) and 14 manvantaras (age of Manu, progenitor of mankind), with each manvantara lasting for 306.72 million years. Each kalpa has 1,000 and each manvantara has 71 chatur-yugas (epoch, a.k.a. maha-yuga), with each chatur-yuga lasting for 4.32 million years and divided into four yugas (dharmic ages): Satya Yuga (1,728,000 years), Treta Yuga (1,296,000 years), Dvapara Yuga (864,000 years), and Kali Yuga (432,000 years), of which we are currently in Kali Yuga.[22][23][24][25][26][27][28][29][30][31]

Life

The individual, spiritual jiva-atma (embodied soul) is the life force or consciousness within a living entity. Jivas are eternal; they are not created or destroyed, and are distinct from the created unconscious matter. The gunas in their manifest state of matter, cover the jivas in various ways based on each jiva's karma and impressions. This material covering of matter allows the jivas to interact with the material sense objects that make up the material universe, such as their temporary material bodies, other conscious bodies, and unconscious objects.[32][33][34]

Material creation is called maya and is characterized as impermanent (non-eternal), sometimes manifest and sometimes not. It has been compared to a dream or virtual reality, where the viewer (jiva) has real experiences with objects that will eventually become unreal.[35][36]

Through the interactions with the material sense objects, a jiva starts to identify the temporary material body as the true self, and in this way becomes influenced and bound by maya perpetually in a conscious state of nescience (ignorance, unawareness, forgetfulness). This conscious state of nescience leads to samsara (cycle of reincarnation), only to end for a jiva when moksha (liberation) is achieved through self-realization (atman-jnana) or remembrance of one's true spiritual self/nature.[37][38][39][40][41] Taking action to develop this state of awareness of ones true identity, and to understand the illusionary nature of maya is known as striving for moksha. Hindus believe that dharma is a means to moksha, thus perfecting dharma is one such action.[42] The spiritual practice known as sadhna is another action.[43] The jiva is considered the place where all positive qualities within us are housed, yet remain hidden due to the "layers of maya".[43]

The different schools of thought differ in understanding about the initial event that led to the jivas entering the material creation and the ultimate state of moksha.

Creation and structure

Hinduism is a group of distinct intellectual or philosophical points of view, rather than a rigid common set of beliefs.[44] It includes a range of viewpoints about the origin of life. Hindu texts do not provide a single canonical account of the creation; they mention a range of theories of the creation of the world, some of which are apparently contradictory.[45]

Rigveda

According to Henry White Wallis, the Rigveda and other Vedic texts are full of alternative cosmological theories and philosophical questions. To its numerous open-ended questions, the Vedic texts present a diversity of thought, in verses imbued with symbols and allegory that sometimes clothe the forces and agencies of the cosmos anthropomorphically with distinct personalities.[46]

Hiranyagarbha sukta (golden egg)

Rigveda 10.121 mentions the Hiranyagarbha ("hiranya = golden or radiant" and "garbha = filled / womb") that existed as the source of the creation of the universe, similar to the world egg motif found in creation myths of many other civilizations.

This metaphor has been interpreted differently by later texts. The Samkhya texts state that Purusha and Prakriti made the embryo, from which the world emerged. In another tradition, the creator god Brahma emerged from the egg and created the world, while in yet another tradition Brahma himself is the Hiranyagarbha.[47] The nature of the Purusha, the creation of the gods and other details of the embryo creation myth have been described variously by the later Hindu texts.

Purusha Sukta

The Purusha Sukta (RV 10.90) describes a myth of proto-Indo-European origin, in which creation arises out of the various body parts of the Purusha, a primeval cosmic being who is part of a yajna by the gods.[48][49] Purusha is described as all that has ever existed and will ever exist.[50] This being's body was the origin of four different kinds of people: the Brahmin, the Rajanya, the Vaishya, and the Shudra.[51] Viraj, variously interpreted as the mundane egg[49] (see Hiranyagarbha) or the twofold male-female energy, was born from Purusha, and the Purusha was born again from Viraj. The gods then performed a yajna with the Purusha, leading to the creation of the other things in the manifested world from his various body parts and his mind. These things included the animals, the Vedas, the Varnas, the celestial bodies, the air, the sky, the heavens, the earth, the directions, and the Gods Indra and Agni.

The later texts such as the Puranas identify the Purusha with God. In many Puranic notes, Brahma is the creator god.[52]:103,318 However, some Puranas also identify Vishnu, Shiva or Devi as the creator.[52]:103

Nasadiya Sukta

The Nasadiya Sukta (RV 10.129) takes a near-agnostic stand on the creation of the primordial beings (such as the gods who performed the sacrifice of the Purusha), stating that the gods came into being after the world's creation, and nobody knows when the world first came into being.[53] It asks who created the universe, does anyone really know, and whether it can ever be known.[54] The Nasadiya Sukta states:[55][56]

Who really knows? Who will here proclaim it?
Whence was it produced? Whence is this creation?
Gods came afterwards, with the creation of this universe.
Who then knows whence it has arisen?

Whether God's will created it, or whether He was mute;
Perhaps it formed itself, or perhaps it did not;
Only He who is its overseer in highest heaven knows,
Only He knows, or perhaps He does not know.
