What is an Avatar?

When a world goes wrong past the point where ordinary repair can save it, when cruelty is in power and the good are crushed and the very order of things is coming apart, the tradition says the divine does not watch from a distance. It comes down. It takes a body, enters the wreckage, and sets the age right from the inside. That coming-down has a name, and the name has since wandered into films and video games, but its origin is one of the great ideas of Hinduism.

The word is avatara, and it means a descent.

The promise in the Gita

The defining statement is short and famous, spoken by Krishna in the fourth chapter of the Bhagavad Gita. In Kashinath Telang’s translation of 1882:

“Whensoever piety languishes, and impiety is in the ascendant, I create myself. I am born age after age, for the protection of the good, for the destruction of evil-doers, and the establishment of piety.”

Telang renders dharma as “piety,” but the meaning is the larger one: whenever dharma, the right order of the world, decays, the divine descends to restore it. And the verse just before is the one that makes the idea precise. Krishna says that though he is aja, unborn, and imperishable in his essence, he is still “born by means of his delusive power.” He does not stop being the unborn absolute. He appears, by his own will, while remaining what he always was.

That single line carries the whole distinctiveness of the idea, and it is worth slowing down on.

A descent, not an incarnation

It is natural for a reader from a Christian background to translate “avatar” as “incarnation,” and natural and wrong. The differences are not small.

An incarnation, in the Christian sense, is a single, unrepeatable event: God becomes man once, irreversibly. An avatara is none of those things. It is repeatable, happening age after age, as the Gita says. It can be multiple, the divine appearing in more than one form. And it leaves the divine unchanged in its own nature: Vishnu descends as Rama, as Krishna, as the boar and the man-lion, and throughout remains the unborn, undiminished absolute. The descent is real, the body is real, the suffering and action are real, and yet the ocean is not emptied by the wave it sends to shore.

It must also be kept clear of reincarnation, with which it is often confused. Reincarnation, punarjanma, is the karma-bound rebirth of an ordinary soul, dragged back into a body by its past deeds. An avatara is the opposite: the free descent of the already-free divine, bound by nothing, choosing to come.

The ten, and the many

The best-known form of the doctrine is the Dashavatara, the ten descents of Vishnu: Matsya the fish, Kurma the tortoise, Varaha the boar, Narasimha the man-lion, Vamana the dwarf, Parashurama, Rama, Krishna, the Buddha, and Kalki, who is still to come at the end of the present dark age. Read in order, they have even been seen as a kind of ascent from water-creature to amphibian to beast to man, though that is a modern reading laid over an older list. The set of ten was given its enduring popular form by the poet Jayadeva, whose twelfth-century Gita Govinda opens with a hymn saluting Vishnu in each of his ten descents, and it is through such devotional verse, more than any single scripture, that the canonical ten settled in the popular mind.

The ten are not the whole story. The Bhagavata Purana lists around two dozen descents and then says plainly that they are beyond counting, like streams from an inexhaustible lake. The ten are the popular, memorable canon, not a closed number, and the lists themselves vary from text to text. The inclusion of the Buddha is the most striking and the most ambivalent: in the Vishnu Purana he descends to mislead rather than to save, a divine deception sent to lead the unworthy away from the Vedas, a sign of how the tradition absorbed and uneasily accounted for its great rival.

One last precision. The avatara doctrine is chiefly a Vaishnava one, the descents of Vishnu. Shiva and the Goddess have their own forms and manifestations, but the technical idea of the periodic descent to rescue the age belongs mainly to the Vishnu tradition.

The two who fill the idea

Two of the ten descents tower over the rest, because two of them got the tradition’s greatest stories. Rama, the prince of Ayodhya, is the avatar of dharma embodied, the man who keeps his word at every ruinous cost, and his life fills the Ramayana. Krishna, cowherd and charioteer and teacher, is the fullest descent of all, and his life runs through the Mahabharata and reaches its summit when, on the eve of battle, he speaks the Bhagavad Gita. It is no accident that the doctrine of the descent is stated most clearly by Krishna himself, an avatar explaining what an avatar is, from inside the body he has taken. For most Hindus the abstract idea of avatara simply is Rama and Krishna, the two faces through which the descending God became most loved.

The descents and the ages

The descent is bound up with the tradition’s vast cycles of time. The world does not decline once and get rescued once; it runs through immense recurring ages, the yugas, sliding from a first age of fullness down to a final dark age, the Kali Yuga, in which order is at its thinnest. The avatars are spaced across this turning, and the list is left open at the far end by Kalki, the descent still to come, who will close the present dark age and turn the wheel back toward a new dawn. The idea of the descent is therefore also a theory of history, a promise that however far an age falls, the fall is never final, because the divine has not finished coming down.

Whose descents, and of what kind

A few distinctions keep the idea precise. The full descent, in which the divine takes a complete embodiment as Rama or Krishna, is a purna-avatara; the tradition also speaks of partial descents, an amsa or a kala, in which only a portion of the divine power enters a being. And the doctrine is not evenly shared. It is centred on Vishnu, whose preserving work makes the periodic rescue of the age his special office. Shiva and the Goddess are no less supreme to their devotees, and their many forms are usually called manifestations rather than avataras in the strict sense, appearances of an ever-present power rather than descents staged against the decline of an age. The vocabulary matters, because it marks what each tradition takes the divine’s relation to history to be.

Why the idea endures

The power of the avatara is that it answers a question every religion faces: is the divine far off, or near? The Hindu answer, in this doctrine, is that when things are at their worst the divine is nearest, willing to take a body and enter the very mess that needs saving. Krishna on the battlefield, Rama in exile, the boar lifting the drowned earth on its tusk: these are pictures of a God who descends.

The age breaks. Something comes down to mend it. That is the whole of the idea, and it is enough.
