Vishnu

From Vedic figure to supreme god

In the Ṛgveda, Viṣṇu is a relatively minor deity, best known for a single striking myth: in three strides he measures out the whole of the universe — earth, atmosphere, and the highest heaven — establishing him from the outset as a god associated with pervading and upholding cosmic space rather than with any one domain of nature. This myth was later literalized in the story of the Vāmana avatar, a dwarf brahmin who tricks the demon king Bali out of the cosmos in three steps. Over the following centuries — through the Brāhmaṇas, the epics, and above all the Purāṇas composed roughly from the early centuries CE onward — Viṣṇu was elevated from a secondary Vedic figure into one of Hinduism's two great sectarian gods, alongside Śiva, around whom the devotional traditions of Vaiṣṇavism and Śaivism crystallized.

Within the Trimūrti, the triad through which classical Hinduism organizes cosmic function, Viṣṇu is assigned the role of preserver: sustaining dharma, the moral and cosmic order, against forces that would unravel it. He is conventionally shown reclining on the coils of the great serpent Śeṣa (or Ananta) upon the cosmic ocean of milk (Kṣīrasāgara) between cycles of creation, with a lotus growing from his navel from which Brahmā is born — a single image that binds the three gods of the Trimūrti into one cosmological picture. His own abode is described as Vaikuṇṭha.

The Daśāvatāra

Viṣṇu is most widely known through his avatars — physical descents to earth undertaken, in his own words in the Bhagavad Gītā, whenever dharma declines and adharma rises. The standard list of ten, the Daśāvatāra, crystallizes relatively late in the Purāṇic literature and includes Matsya, a fish who saves the sacred scriptures and the first man, Manu, from a great flood; Kūrma, a tortoise who supports Mount Mandara during the churning of the cosmic ocean; Varāha, a boar who lifts the earth from the ocean floor; Narasiṃha, a man-lion who kills the demon Hiraṇyakaśipu, exploiting a boon that the demon could not be killed by man or beast, indoors or outdoors, by day or night; Vāmana, the dwarf who reclaims the cosmos from Bali in three strides; Paraśurāma, an axe-wielding warrior-sage who punishes an oppressive kṣatriya class; Rāma, hero of the Rāmāyaṇa and paradigm of righteous kingship; Kṛṣṇa, strategist of the Mahābhārata war and speaker of the Bhagavad Gītā; the Buddha, included in some Vaiṣṇava lists (and replaced by Balarāma in others) as a form taken to curb excessive ritual violence; and Kalki, a warrior yet to come, prophesied in the Purāṇas to appear at the end of the current age riding a white horse to destroy evil and reset the cycle of time.

Iconography

Viṣṇu is typically shown as a blue-skinned figure with four arms, crowned and richly ornamented, holding his four principal emblems: the śaṅkha (conch), associated with the primordial sound of creation; the Sudarśana Chakra (discus), a weapon turned against evil and a symbol of the mind's power; the gadā (mace), representing physical and mental strength; and the padma (lotus), representing purity and the unfolding of the created world. His mount, Garuḍa, a giant eagle-like being, embodies speed and martial power, and his consort Lakṣmī, goddess of wealth and prosperity, reinforces his character as sustainer of the world's welfare.

Vaiṣṇavism

Within Vaiṣṇavism, Viṣṇu is worshipped not merely as one deity among many but as the supreme being, Paramātmā, of whom other gods are aspects or attendants. The Bhagavad Gītā, in which Kṛṣṇa reveals to the warrior Arjuna a terrifying and overwhelming vision of his universal form (viśvarūpa) containing all beings and all time, is central to this theology. Devotion to Viṣṇu's avatars, above all Rāma and Kṛṣṇa, drove much of the medieval bhakti movement, articulated by the twelve Tamil poet-saints known as the Āḻvārs (roughly sixth to ninth century CE), whose hymns were later collected as the Nālāyira Divya Prabandham, and systematized philosophically by figures including Rāmānuja (eleventh–twelfth century, Viśiṣṭādvaita, based at Srirangam), Madhvācārya (thirteenth century, Dvaita, based at Udupi), Nimbārka, Vallabhācārya (Puṣṭimārga), and Caitanya (sixteenth century, Gauḍīya Vaiṣṇavism, centred on Kṛṣṇa devotion in Bengal). Major centres of Viṣṇu worship today include Tirupati in Andhra Pradesh, Jagannātha Puri in Odisha (site of the annual Ratha Yātrā chariot procession), Srirangam in Tamil Nadu, and Badrinath in the Himalayas, and the Viṣṇu Sahasranāma, a hymn of a thousand names delivered by the dying Bhīṣma in the Mahābhārata's Anuśāsana Parva, remains a widely recited devotional text.
