Indra (//, Sanskrit: इन्द्र) is a Vedic deity in Hinduism, a guardian deity (Indā, Pālī) in Buddhism, and the king of the highest heaven called Saudharmakalpa in Jainism. His mythologies and powers are similar to other Indo-European deities such as Jupiter, Perun, Perkūnas, Taranis, Zeus, and Thor.
In the Vedas, Indra is the king of Svarga (Heaven) and the Devas. He is the god of the heavens, lightning, thunder, storms, rains, river flows, and war. Indra is the most referred to deity in the Rigveda. He is celebrated for his powers, and the one who kills the great symbolic evil (malevolent type of Asura) named Vritra who obstructs human prosperity and happiness. Indra destroys Vritra and his "deceiving forces", and thereby brings rains and the sunshine as the friend of mankind. His importance diminishes in the post-Vedic Indian literature where he is depicted as a powerful hero but one who is getting in trouble with his drunken, hedonistic and adulterous ways, and the god who disturbs Hindu monks as they meditate because he fears self-realized human beings may become more powerful than him.
Indra rules over the much sought Devas realm of rebirth within the Samsara doctrine of Buddhist traditions. However, like the Hindu texts, Indra also is a subject of ridicule and reduced to a figurehead status in Buddhist texts, shown as a god that suffers rebirth and redeath. In the Jainism traditions, like Buddhism and Hinduism, Indra is the king of gods and a part of Jain rebirth cosmology. He is also the god who appears with his wife Indrani to celebrate the auspicious moments in the life of a Jain Tirthankara, an iconography that suggests the king and queen of gods reverentially marking the spiritual journey of a Jina.
Indra's iconography shows him wielding a lightning thunderbolt known as Vajra, riding on a white elephant known as Airavata. In Buddhist iconography the elephant sometimes features three heads, while Jaina icons sometimes show the elephant with five heads. Sometimes a single elephant is shown with four symbolic tusks. Indra's heavenly home is on or near Mount Meru (also called Sumeru).

Etymology and nomenclature
The etymological roots of Indra are unclear, and it has been a contested topic among scholars since the 19th-century, one with many proposals. The significant proposals have been:
- root ind-u, or "rain drop", based on the Vedic mythology that he conquered rain and brought it down to earth.
- root ind, or "equipped with great power". This was proposed by Vopadeva.
- root idh or "kindle", and ina or "strong".
- root indha, or "igniter", for his ability to bring light and power (indriya) that ignites the vital forces of life (prana). This is based on Shatapatha Brahmana.
- root idam-dra, or "It seeing" which is a reference to the one who first perceived the self-sufficient metaphysical Brahman. This is based on Aitareya Upanishad.
- roots in ancient Indo-European, Indo-Aryan deities. For example, states John Colarusso, as a reflex of proto-Indo-European *h₂nḗr-, Greek anēr, Sabine nerō, Avestan nar-, Umbrian nerus, Old Irish nert, Ossetic nart, and others which all refer to "most manly" or "hero".
Colonial era scholarship proposed that Indra shares etymological roots with Zend Andra derived from Old High German Antra, or Jedru of Old Slavonic, but Max Muller critiqued these proposals as untenable. Later scholarship has linked Vedic Indra to the European Aynar (the Great One), Abaza, Ubykh and Innara of Hittite mythology. Colarusso suggests a Pontic[note 1] origin and that both the phonology and the context of Indra in Indian religions is best explained from Indo-Aryan roots and a Circassian etymology (i.e. *inra).
For other languages, he is also known as
- Bengali: ইন্দ্র (Indra)
- Burmese: သိကြားမင်း (pronounced [ðadʑá mɪ́ɴ])
- Chinese: 帝释天 (Dìshìtiān)
- Japanese: 帝釈天 (Taishakuten).

Indra has many epithets in the Indian religions, notably Śakra (शक्र, powerful one), Vṛṣan (वृषन्, mighty), Vṛtrahan (वृत्रहन्, slayer of Vṛtra), Meghavāhana (मेघवाहन, he whose vehicle is cloud), Devarāja (देवराज, king of deities), Devendra (देवेन्द्र, the lord of deities), Surendra (सुरेन्द्र, chief of deities), Svargapati (स्वर्गपति, the lord of heaven), Vajrapāṇī (वज्रपाणि, he who has thunderbolt (Vajra) in his hand) and Vāsava (वासव, lord of Vasus).
Indra is of ancient but unclear origin. Aspects of Indra as a deity are cognate to other Indo-European gods; they are either thunder gods such as Thor, Perun, and Zeus who share parts of his heroic mythologies, act as king of gods, and all are linked to "rain and thunder". The similarities between Indra of Hindu mythologies and of Thor of Nordic and Germanic mythologies are significant, states Max Muller. Both Indra and Thor are storm gods, with powers over lightning and thunder, both carry hammer or equivalent, for both the weapon returns to their hand after they hurl it, both are associated with bulls in the earliest layer of respective texts, both use thunder as a battle-cry, both are heroic leaders, both protectors of mankind, both are described with legends about "milking the cloud-cows", both are benevolent giants, gods of strength, of life, of marriage and the healing gods, both are worshipped in respective texts on mountains and in forests.
Michael Janda suggests that Indra has origins in the Indo-European *trigw-welumos [or rather *trigw-t-welumos] "smasher of the enclosure" (of Vritra, Vala) and diye-snūtyos "impeller of streams" (the liberated rivers, corresponding to Vedic apam ajas "agitator of the waters"). Brave and heroic Innara or Inra, which sounds like Indra, is mentioned among the gods of the Mitanni, a Hurrian-speaking people of Hittite region.
Indra as a deity had a presence in northeastern Asia minor, as evidenced by the inscriptions on the Boghaz-köi clay tablets dated to about 1400 BCE. This tablet mentions a treaty, but its significance is in four names it includes reverentially as Mi-it-ra, U-ru-w-na, In-da-ra and Na-sa-at-ti-ia. These are respectively, Mitra, Varuna, Indra and Nasatya-Asvin of the Vedic pantheon as revered deities, and these are also found in Avestan pantheon but with Indra and Naonhaitya as demons. This at least suggests that Indra and his fellow deities were in vogue in South Asia and Asia minor by about mid 2nd-millennium BCE.
Indra is praised as the highest god in 250 hymns of the Rigveda – a Hindu scripture dated to have been composed sometime between 1700 and 1100 BCE. He is co-praised as the supreme in another 50 hymns, thus making him one of the most celebrated Vedic deities. He is also mentioned in ancient Indo-Iranian literature, but with a major inconsistency when contrasted with the Vedas. In the Vedic literature, Indra is a heroic god. In the Avestan (ancient, pre-Islamic Iranian) texts such as Vd. 10.9, Dk. 9.3 and Gbd 27.6-34.27, Indra – or accurately Andra – is a gigantic demon who opposes truth.[note 2] In the Vedic texts, Indra kills the archenemy and demon Vritra who threatens mankind. In the Avestan texts, Vritra is not found.
Indra is called vr̥tragʰná- (literally, "slayer of obstacles") in the Vedas, which corresponds to Verethragna of the Zoroastrian noun verethragna-. According to David Anthony, the Old Indic religion probably emerged among Indo-European immigrants in the contact zone between the Zeravshan River (present-day Uzbekistan) and (present-day) Iran. It was "a syncretic mixture of old Central Asian and new Indo-European elements", which borrowed "distinctive religious beliefs and practices" from the Bactria–Margiana Culture. At least 383 non-Indo-European words were found in this culture, including the god Indra and the ritual drink Soma. According to Anthony,
Many of the qualities of Indo-Iranian god of might/victory, Verethraghna, were transferred to the god Indra, who became the central deity of the developing Old Indic culture. Indra was the subject of 250 hymns, a quarter of the Rig Veda. He was associated more than any other deity with Soma, a stimulant drug (perhaps derived from Ephedra) probably borrowed from the BMAC religion. His rise to prominence was a peculiar trait of the Old Indic speakers.
Indra was a prominent deity in the Vedic era of Hinduism.
Over a quarter of the 1,028 hymns of the Rigveda mention Indra, making him the most referred to deity than any other. These hymns present a complex picture of Indra, but some aspects of Indra are oft repeated. Of these, the most common theme is where he as the god with thunderbolt kills the evil serpent Vritra that held back rains, and thus released rains and land nourishing rivers. For example, the Rigvedic hymn 1.32 dedicated to Indra reads:
इन्द्रस्य नु वीर्याणि प्र वोचं यानि चकार प्रथमानि वज्री ।
Let me tell you the manly deeds of Indra, which he first accomplished, bolt-weaponed,
The hymns of Rigveda declare him to be the "king that moves and moves not", the friend of mankind who holds the different tribes on earth together. In one interpretation by Oldenberg, the hymns are referring to the snaking thunderstorm clouds that gather with bellowing winds (Vritra), Indra is then seen as the storm god who intervenes in these clouds with his thunderbolts, which then release the rains nourishing the parched land, crops and thus humanity. In another interpretation by Hillebrandt, Indra is a symbolic sun god (Surya) and Vritra is a symbolic winter-giant (historic mini cycles of ice age, cold) in the earliest, not the later, hymns of Rigveda. The Vritra is an ice-demon of colder central Asia and northern latitudes, who holds back the water. Indra is the one who releases the water from the winter demon, an idea that later metamorphosed into his role as storm god. According to Griswold, this is not a completely convincing interpretation, because Indra is simultaneously a lightning god, a rain god and a river-helping god in the Vedas. Further, the Vritra demon that Indra slew is best understood as any obstruction, whether it be clouds that refuse to release rain or mountains or snow that hold back the water.
Even though Indra is declared as the king of gods in some verses, there is no consistent subordination of other gods to Indra. In Vedic thought, all gods and goddesses are equivalent and aspects of the same eternal abstract Brahman, none consistently superior, none consistently inferior. All gods obey Indra, but all gods also obey Varuna, Vishnu, Rudra and others when the situation arises. Further, Indra also accepts and follows the instructions of Savitr (solar deity). Indra, like all Vedic deities, is a part of henotheistic theology of ancient India.
Indra is not a visible object of nature in the Vedic texts, nor is he a personification of any object, but that agent which causes the lightning, the rains and the rivers to flow. His myths and adventures in the Vedic literature are numerous, ranging from harnessing the rains, cutting through mountains to help rivers flow, helping land becoming fertile, unleashing sun by defeating the clouds, warming the land by overcoming the winter forces, winning the light and dawn for mankind, putting milk in the cows, rejuvenating the immobile into something mobile and prosperous, and in general, he is depicted as removing any and all sorts of obstacles to human progress. The Vedic prayers to Indra, states Jan Gonda, generally ask "produce success of this rite, throw down those who hate the materialized Brahman".
Indra is often presented as the twin brother of Agni (fire) – another major Vedic deity. Yet, he is also presented to be the same, states Max Muller, as in Rigvedic hymn 2.1.3, which states, "Thou Agni, art Indra, a bull among all beings; thou art the wide-ruling Vishnu, worthy of adoration. Thou art the Brahman, (...)." He is also part of one of many Vedic trinities as "Agni, Indra and Surya", representing the "creator-maintainer-destroyer" aspects of existence in Hindu thought.[note 3]
The ancient Aitareya Upanishad equates Indra, along with other deities, with Atman (soul, self) in the Vedanta's spirit of internalization of rituals and gods. It begins with its cosmological theory in verse 1.1.1 by stating that, "in the beginning, Atman, verily one only, was here - no other blinking thing whatever; he bethought himself: let me now create worlds". This soul, which the text refers to as Brahman as well, then proceeds to create the worlds and beings in those worlds wherein all Vedic gods and goddesses such as sun-god, moon-god, Agni and other divinities become active cooperative organs of the body. The Atman thereafter creates food, and thus emerges a sustainable non-sentient universe, according to the Upanishad. The eternal Atman then enters each living being making the universe full of sentient beings, but these living beings fail to perceive their Atman. The first one to see the Atman as Brahman, asserts the Upanishad, said, "idam adarsha or "I have seen It". Others then called this first seer as Idam-dra or "It-seeing", which over time came to be cryptically known as "Indra", because, claims Aitareya Upanishad, everyone including the gods like short nicknames. The passing mention of Indra in this Upanishad, states Alain Daniélou, is a symbolic folk etymology.
The section 3.9 of the Brihadaranyaka Upanishad connects Indra to thunder, thunderbolt and release of waters. In section 5.1 of the Avyakta Upanishad, Indra is praised as he who embodies the qualities of all gods.
In post-Vedic texts, Indra is depicted as an intoxicated hedonistic god, his importance declines, and he evolves into a minor deity in comparison to others in the Hindu pantheon, such as Shiva, Vishnu, or Devi. In Hindu texts, Indra is some times known as an aspect (avatar) of Shiva.
He is depicted as the father of Vali in the Ramayana and Arjuna in the Mahabharata. He becomes a source of nuisance rains in the Puranas, out of anger and with an intent to hurt mankind. But, Krishna as an avatar of Vishnu, comes to the rescue by lifting Mount Govardhana on his fingertip, and letting mankind shelter under the mountain till Indra exhausts his anger and relents. Also, according to Mahabharata Indra, disguised himself as a Brahmin approached Karna and asked for his kavach and kundal as a charity. Although being aware of his true identity, Karna peeled off his kavach and kundal and fulfilled the wish of Indra. Pleased by this act Indra gifted Karna a dart called Vasavi Shakthi.
Sangam literature (300 BCE–300 AD)
Sangam literature of the Tamil language contains more stories about Indra by various authors. In Silapathikaram Indra is described as Maalai venkudai mannavan (மாலைவெண் குடை மன்னவன்), literally meaning Indra with the pearl-garland and white umbrella.
The Sangam literature also describes Indhira Vizha (festival for Indra), the festival for want of rain, celebrated for one full month starting from the full moon in Ootrai (later name – Cittirai) and completed on the full moon in Puyaazhi (Vaikaasi) (which coincides with Buddhapurnima). It is described in the epic Cilapatikaram in detail.
Relations with other gods
In the Hindu religion, he is married to Shachi, also known as Indrani or Pulomaja.
In the Brahmavaivarta Purana, Indra defeats Vṛtrá and releases the waters. Indra asks Vishvakarma to build him a palace, but ultimately decides to leave his life of luxury to become a hermit and seek wisdom. Horrified, Indra's wife Shachi asks the priest Brihaspati to change her husband's mind. He teaches Indra to see the virtues of both the spiritual life and the worldly life. Thus, at the end of the story, Indra learns how to pursue wisdom while still fulfilling his kingly duties.
In Rigveda, Indra is described as strong willed, armed with a thunderbolt, riding a chariot:
May the strong Heaven make thee the Strong wax stronger: Strong, for thou art borne by thy two strong Bay Horses. So, fair of cheek, with mighty chariot, mighty, uphold us, strong-willed, thunder armed, in battle.— RigVeda, Book 5, Hymn XXXVI: Griffith
Indra's weapon, which he used to kill evil Vritra, is the Vajra or thunderbolt. Other alternate iconographic symbolism for him includes a bow (sometimes as a colorful rainbow), a sword, a net, a noose, a hook, or a conch. The thunderbolt of Indra is called Bhaudhara.
In the post-Vedic period, he rides a large, four-tusked white elephant called Airavata. In sculpture and relief artworks in temples, he typically sits on an elephant or is near one. When he is shown to have two, he holds the Vajra and a bow.
The Buddhist cosmology places Indra above Mount Sumeru, in Trayastrimsha heaven. He resides and rules over one of the six realms of rebirth, the Devas realm of Saṃsāra, that is widely sought in the Buddhist tradition.[note 4] Rebirth in the realm of Indra is a consequence of very good Karma (Pali: kamma) and accumulated merit during a human life.
In Buddhism, Indra is commonly called by his other name, Śakra or Sakka, ruler of the Trāyastriṃśa heaven. Śakra is sometimes referred to as Devānām Indra or "Lord of the Devas". Buddhist texts also refer to Indra by numerous names and epithets, as is the case with Hindu and Jain texts. For example, Asvaghosha's Buddhacarita in different sections refers to Indra with terms such as "the thousand eyed", Puramdara, Lekharshabha, Mahendra, Marutvat, Valabhid and Maghavat. Elsewhere, he is known as Devarajan (literally, "the king of gods"). These names reflect a large overlap between Hinduism and Buddhism, and the adoption of many Vedic terminology and concepts into Buddhist thought. Even the term Śakra, which means "mighty", appears in the Vedic texts such as in hymn 5.34 of the Rigveda.
The Bimaran Casket made of gold inset with garnet, dated to be around 60 CE, but some proposals dating it to the 1st century BCE, is among the earliest archaeological evidences available that establish the importance of Indra in Buddhist mythology. The artwork shows the Buddha flanked by gods Brahma and Indra.
In China, Korea, and Japan, he is known by the characters 帝釋天 (Chinese: 釋提桓因, pinyin: shì dī huán yīn, Korean: "Je-seok-cheon" or 桓因 Hwan-in, Japanese: "Tai-shaku-ten", kanji: 帝釈天). In Japan, Indra always appears opposite Brahma (梵天, Japanese: "Bonten") in Buddhist art. Brahma and Indra are revered together as protectors of the historical Buddha (Chinese: 釋迦, kanji: 釈迦, also known as Shakyamuni), and are frequently shown giving the infant Buddha his first bath. Although Indra is often depicted like a bodhisattva in the Far East, typically in Tang dynasty costume, his iconography also includes a martial aspect, wielding a thunderbolt from atop his elephant mount.
In Japan, Indra is one of the twelve Devas, as guardian deities, who are found in or around Buddhist temples (Jūni-ten, 十二天). In Japan, Indra has been called "Taishaku-ten". He joins these other eleven Devas of Buddhism, found in Japan and other parts of southeast Asia: Agni (Ka-ten), Yama (Enma-ten), Nirrti (Rasetsu-ten), Vayu (Fu-ten), Ishana (Ishana-ten), Kubera (Tamon-ten), Varuna (Sui-ten), Brahma (Bon-ten), Prithvi (Chi-ten), Surya (Nit-ten), and Chandra (Gat-ten).
Indra in Jain mythology always serves the Tirthankara teachers. Indra most commonly appears in stories related to Tirthankaras, in which Indra himself manages and celebrates the five auspicious events in that Tirthankara's life, such as Chavan kalyanak, Janma kalyanak, Diksha kalyanak, Kevala Jnana kalyanak, and moksha kalyanak.
There are sixty-four Indras in Jaina literature, each ruling over different heavenly realms where heavenly souls who have not yet gained Kaivalya (moksha) are reborn according to Jainism. Among these many Indras, the ruler of the first Kalpa heaven is the Indra who is known as Saudharma in Digambara, and Sakra in Śvētāmbara tradition. He is most preferred, discussed and often depicted in Jaina caves and marble temples, often with his wife Indrani. They greet the devotee as he or she walks in, flank the entrance to an idol of Jina (conqueror), and lead the gods as they are shown celebrating the five auspicious moments in a Jina's life, including his birth. These Indra-related stories are enacted by laypeople in Jainism tradition during special Puja (worship) or festive remembrances.
- near Black Sea.
- In deities that are similar to Indra in the Hittite and European mythologies, he is also heroic.
- The Trimurti idea of Hinduism, states Jan Gonda, "seems to have developed from ancient cosmological and ritualistic speculations about the triple character of an individual god, in the first place of Agni, whose births are three or threefold, and who is threefold light, has three bodies and three stations". Other trinities, beyond the more common "Brahma, Vishnu, Shiva", mentioned in ancient and medieval Hindu texts include: "Indra, Vishnu, Brahmanaspati", "Agni, Indra, Surya", "Agni, Vayu, Aditya", "Mahalakshmi, Mahasarasvati, and Mahakali", and others.
- Scholars note that better rebirth, not nirvana, has been the primary focus of a vast majority of lay Buddhists. This is sought in the Buddhist traditions through merit accumulation and good kamma.
